According to ASTM ferrous metal designation system, “A” describes a ferrous metal such as A106, "A" prefix indicates that this material is ferrous material. The Cast Iron thus obtained is in a molten state, and it is chilled, i.e., it is cooled rapidly. As the most common types of ferrous metals, steel waste is recycled to the most. 5. The slag is removed intermittently through the hole and molten metal taken out through its tap hole. • It is typical of this group that Iron (Fe) in one form or another, is the principle component of all ferrous materials. become misaligned, … Besides the ecological benefit of metal recycling there is also an economical benefit. Metal cuttings or imperfect products are recycled by remelting, recasting, and redrawing entirely within the steel mill. While the process for making aluminum is a bit more complicated than some of the other metals, it’s actually an extremely common metal. It is used for automobile cylinder blocks, heads, housings, etc. Chromium makes the Cast Iron extremely tough, strong and ductile. Cast Iron is manufactured in a furnace known as cupola furnace. Steel is superior in resisting both compressive and tensile stresses. The source material for the manufacture of Wrought Iron is PIG IRON. The Iron obtained is known as Cast Iron, and the shapes obtained are called Cast Iron castings. 3. Carbon Steel. Steel is manufactured using one of the following processes: Steels can be classified in many ways such as on the basis of the methods used in their manufacture, on the carbon content, or according to their use. These facts explain the reason that for the considerable time, the annual global production of Ferrous Metals has been far in excess than the combined production of all Non-Ferrous Metals produced in all the countries of the world. Steel is an alloy of Iron and carbon, where the carbon content is less than 1.7%. The most common ferrous metals are mild steel, carbon steel, alloy steel, stainless steel, wrought iron and cast iron. This is the first major group of Steels. Carbon steel is a ferrous alloy with 0.05 to 2.0% carbon, and is known for its high … The working of the furnace or manufacturing of Cast Iron is as follows: The mixture of Pig Iron, coke, and limestone, known as a charge, is prepared in correct proportions. Also known as uniform attack corrosion, general attack corrosion is the most common type of corrosion and is caused by a chemical or electrochemical reaction that results in the deterioration of the entire exposed surface of a metal. It is used for pipe and pipe fittings. The ultimate compressive strength ranges between 1500-2000 kg/cm2. Better results are obtained when Pig Iron with alloying elements are heated in an electric furnace or air furnace. 2. 2. The best thing about Steel is that it has both properties of Cast and Wrought Iron – Compressive Strength of Cast Iron and Tensile Strength of Wrought Iron. It shows grey color when fractured. 2. White iron. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide] This is explained by a number of reasons: 1. If there is a free graphite present, it is a Cast Iron, otherwise a Steel. It is,... 2. 8. Thus all the Steels, in addition to Iron and carbon-containing other elements such as; nickel, chromium, manganese, silicon, vanadium, molybdenum, tungsten, sulfur, phosphorus, etc., are called as alloy Steels. Alloy steels contain low to high levels of elements such as chromium, molybdenum, vanadium and nickel. White cast iron. It is not easily machinable due to its hardness, hence, require special tools for machining. Metal recycling is the process of separating, cleaning and melting ferrous and non-ferrous scrap so it can be used again as a raw material for new products. 4. It is, therefore, impure and crude and requires subsequent processing to develop Cast, Wrought Iron, and Steel, which are the common Ferrous Metals used in construction and industries. 2. 5. Ferrous Metals List | Their Types and Properties: What is Paint, Definition, Properties, & Components of paints. The resistance against very high temperature, abrasion and corrosion may be improved considerably. Iron is actually the only metal that “rusts” by definition. These are Steels made with the addition of a definite proportion of a selected element or elements in addition to carbon at the manufacturing stage. The outer shell is made of Steel. Used for making parts, bodies, and beds of machines. 3. Therefore, Pig Iron is remolded in a furnace and cast or poured into molds of the desired shape to get the Iron known as Cast Iron. So, while metals like iron, copper and aluminum are easily detectable, you … These metals are not magnetic, which is one way you can determine for yourself what type of scrap metal you are dealing with. Alloy steels are a type of ferrous metal specially formulated to serve specific purposes. Cast Iron is derived from the Pig Iron. or other elements added, to give the required. Alloy steel. It is, however, the classification on the basis of their chemical composition is commonly adopted. Ferrous metals emerged much later when iron production started around 1,200 BC. Pig Iron is the first or basic form in which Iron is prepared as the metal from its ores. Different types can be cast, hot forged, cold-forged, cold-rolled into sheets, drawn into wires and extrusions for cross-section bars. It is weak in tension and strong in compression. On the other hand, with the decrease in the carbon content (lower than 0.1%), the material would resemble more to Wrought Iron or pure Iron. Iron (Fe) is the principal element of Ferrous Metals. The purpose of alloying is to improve the properties of Steel, like imparting the fine grain size, to improve the hardness, toughness, strength, corrosion resistance, etc. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide] It is used in Agricultural machinery making and carpentry tools. 2. Because of the above set of properties, Wrought Iron is extensively used as a material for making plates, sheets, pipes, tubes, etc. Ferrous and nonferrous are two important classifications of metals. Following are the major groups of Steels. As the name indicates these are the metal combination of Iron with carbon. METALS. Pig Iron, because of its impurities, is weak and hence very difficult to shape into various forms. Some examples are chromium, nickel, molybdenum, vanadium, manganese. It is used for car wheels, rollers for crushing grains, crusher jaw plates, etc. An alloy is the purposeful mixture of two or more elements of which one being in largest proportion is called as base metal, and other elements are called as alloying elements. Ferrous Metals List | Their Types and Properties: 1. It is suitable for highly corrosive environments such as: liquid, chemical and sewage pipelines. In white Cast Iron, the entire carbon is in combined state. The carburization and reduction of the ore with Coke. 3. A good metal detector can detect both ferrous and non-ferrous metals, though non-ferrous metals are twice as hard to detect. The cupola furnace contains a charging door, a platform and tapping holes for the purpose of blasting the air. The Iron obtained is malleable as well as ductile. Wrought Iron shows good resistance to fatigue and sudden shock. However, non-ferrous metals all do have one thing in common: They do not rust. Types Of Metals. The Importance of Guard and Hand Rails In Industrial Workplace Safety, Precast Concrete: Its Types, Advantages, Manufacturing. Why is it that ferrous Alloys have low electrical conductivity. Wrought Iron:. 4. It is specially used in the manufacture of Steel in the Bessemer process, because of its freedom from sulfur and phosphorous. The term ferrous, derived from Latin ferrum, is used in metallurgy to indicate the presence or absence of iron.Thus, the main difference between ferrous metals and nonferrous metals is their iron content; ferrous metals contain iron as a component whereas … Cast Iron:. It has high tensile strength, toughness, and wear resistance. Therefore, it is also known as chilled Cast Iron. (β-phase is less ductile than α -phase, but it is stronger and harder. This categorization is based on the iron content. It is poor in tensile strength and impact strength with almost no ductility. White Cast Iron is produced by melting the low phosphorus Pig Iron along with the Steel scraps in a cupola furnace. About 60% less energy is required to produce steel from recycled materials than its production from iron. The tensile strength of the Steel may be increased without affecting its workability. The division of metals into two groups – ferrous and non-ferrous – has been formed historically. In all the jobs ranging from the manufacture of a primitive type of agricultural implements to advanced types of Air Crafts, ferrous metals and their alloys occupy a prominent position. Used in compression members, bed plates, etc. The ferrous materials include carbon steel, stainless steel, and low alloy steel. However, the Steel, containing Iron and carbon, is not referred to as an alloy. Metal is a material which can be recycled over and over again without degradation of its properties. The tensile strength of malleable Cast Iron is higher than that of grey Cast Iron and has good machinability. Alloy Cast Irons are also called as plain Cast Irons. Moreover, it can be welded with ease. As we noted earlier, Cast Iron is better in resisting compressive stresses, while Wrought Iron is suited to tensile stresses. Ferrous metallurgy represents roughly 90% of worldwide production of metal. Beyond 30% Zinc, the tensile strength increases up to 45% of Zinc, but the ductility significantly drops. Usually magnetic 4. Gray iron is the most common metal cast in foundries. If you have any questions, feel free to ask in the comment section. Great tensile strength 3. The grey color is due to the presence of free graphite. They may have small amounts of other metals. It is white in color as there is no free graphite. Outside of the foundry, steel is the ferrous … What are iron alloys? But if elements are added other than Iron and carbon, the Steel is known as alloy Steel. Cannot be tempered or hardened like steel. Carbon is the only controlling component in them besides Iron. Non-ferrous metals, depending on their properties and distribution, are divided into four groups: 1. It is very strong, hard, and resistant to Wear and Tear. It is malleable, ductile, tough, and resistant to corrosion. Types of Ferrous Metals Mild steel and Carbon steel: Iron is combined with carbon to obtain mild steel and carbon steel. iron. The molten metal in almost pure form is collected at the bottom of the furnace along with the floating slag. For example aluminium, copper, lead, nickel, tin, titanium and zinc. 4. When iron cools and changes from a liquid to a solid, most of the atoms in the metal pack, tightly together in orderly layers. That means each type of ferrous and non-ferrous metal has different qualities and uses. The economic extraction of Iron from its ore. 3. The first steel pieces were found in modern-day Turkey and date back to 1,800 BC. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide]. Pig iron. 2. Non-ferrous metals are used because of its properties such as higher conductivity (e.g. Its properties can be varied over a wide range by varying its composition and by subjecting it to various mechanical and heat treatment processes. Recyclable 7. The elements of the composition of Steel apart from carbon are sulfur, silicon, phosphorus, manganese, etc. Abrasive Definition and Types of Abrasives its Forms and Applications. Some, however. The Cast Iron thus obtained, has 1.7 to 4% of carbon with small impurities of manganese, phosphorus, silicon, and sulfur. zinc). Wrought iron. Non-ferrous metals are also more resilient when compared to ferrous ones. Physical: Wrought Iron is bluish in color, has a silky luster and fibrous structure. Formwork (Shuttering) for Concrete [Its Types, Design]. It possesses useful properties of both Cast Iron and mild Steels. The process is much cheaper than producing new metal from the basic ore. There are far more differences than there are similarities among the different types of non-ferrous metals. Ferrous Metals • The ferrous group of metal include all types of Iron, Steel, and their alloys. What is Scaffolding? While composed primarily of iron, differing amounts of copper, vanadium, tungsten, manganese, and other elements can be used to tailor an alloy steel to have higher toughness, ductility, tensile strength, hardness, and other properties. It can be hardened but cannot be tempered. Ferrous and non-ferrous metals are two different types of metals. Grey Cast Iron is produced by melting the foundry Pig Iron or grey Pig Iron in the cupola furnace.

Brinell hardness number of 105; tensile strength of 35,000 psi; specific gravity of 7.7; a melting point of 2750°F (1510°C); and is ductile and corrosion resistant. They are further subdivided into 3 subcategories. If the carbon content in Steel exceeds 1.7%, it does not combine with the Iron, but it is present as free graphite. Gray cast iron. The hardness and toughness of Steel increase with the increase in carbon content up to 1.7%. It’s often mixed with other metals to produce another type of metal like bronze and brass. Ferrous Metals Ferrous metals contain iron, and are known for their strength. What is metal recycling? It is used for castings where shock and impact loads are operating. This is a heavy metal that’s dull grey in color, although it becomes shiny when polished. Examples of ferrous metals include carbon steel, mild steel, stainless steel, cast iron and wrought iron. 2. It is also called forge Pig Iron, as it is hard and brittle and can be converted only by using pressure. Test for Compressive Strength of Bricks, Absorption, Efflorescence & Size. Steel is a versatile material of modern age. Below are a few of the types of finishing processes available: Plating. On the basis of the presence of free graphite, differentiation of Steel and Cast Iron can be made. The wide abundance of Iron ore in almost all parts of the world. Its Types, Parts Used in Construction. Besides carbon, many other metals may also be present in addition to Iron, giving rise to great varieties of Steel. Used for rail chairs, carriage wheels, etc. 1. The flexibility that can be induced in the mechanical properties of Iron by combining it with other metals and/or by heat treatment and such other methods. Types of metals and their uses. Malleable Cast Iron is the annealed White Cast Iron, i.e., white Cast Iron is heated slowly up to 900 to 950°C temperature for several days and then cooled at a slower rate. Main Difference – Ferrous Metals vs Nonferrous Metals. The metal which is consisting of the main constituent other than the iron is known as Non-ferrous metals. A list of ferrous metal properties: 1. It has high tensile strength but weak compressive strength. ... Non-ferrous metal that is strong and ductile, casts well and is gold coloured but darkens when oxidised with age, a good conductor of heat: Pure Iron is of little use as an engineering material because it is too soft and ductile. 4. The strength will be greater in the longitudinal direction. Types of Metal Finishing. It is also called as nodular or spheroid graphite Cast Iron or high strength Cast Iron. Non-ferrous metals are those which do not contain significant quantity of iron (ferrite) or iron as the base metal. It cannot be tempered or hardened like steel. 1. automotive parts: engine blocks, pistons, gearbox cases, cylinder blocks, No Alloys: Tensile strength of 25,000 to 50,000 psi (172,375 to 344,750 kPa), Alloys: 50,000 to 100,000 psi (344,750 to 689,500 kPa), Cylinder heads for compressors and diesel engines.

It’s non-ferrous and it has a density of 8.94 g/cm3. Steel is an iron-based alloy containing typically less than 1% carbon, where iron frequently contains 2% or more carbon. They can be sub-divided into 2 types on the basis of the proportion of alloying elements, which are the following: Read More: In this article, you are going to learn in details, that what is Ferrous Metal? The types of coins you might discover depend entirely upon the metal. Cast Iron is derived from the Pig Iron. And in any other field of engineering activity, it may not be possible to move ahead without metals. The top of the furnace remains open. Chilled cast iron. Non-ferrous items tend to last longer because they are more resistant to corrosion and rust. Pig Iron is the first or basic form in which Iron is prepared as the metal from its ores. It can also be classified on the basis of Steel casting. All ferrous metals are magnetic and. It cannot be forged, welded, or riveted. It is used for hubs of wagon wheels, railway rolling stock, brake supports, parts of agricultural machinery, pipe fittings, door hinges, locks, etc. And quite brittle as well. Alloyed Cast Irons are produced by adding the alloying elements to the Pig Iron in the cupola furnace itself or adding the same into the molten Cast Iron taken out of the furnace. i.e., in the form of cementite, also known as Iron carbide. 2. Malleable cast iron. Think steel, stainless steel, carbon steel, cast iron. It is the purest form of Iron, containing all impurities below a limit of 0.5 percent. Durable 2. The electrical, magnetic, and thermal properties may be modified in the desired direction. This type contains sulfur as the main impurity and hence is considered inferior in grade. It is used in rolls for rolling mills, hydraulic cylinders, cylinder heads, etc. Examples of ferrous metals uses: Because these metals tend to be strong and durable, they have many uses in construction and engineering.

Hence, Steel finds most of the applications for all purposes in places of Cast Iron and Wrought Iron. Please, don’t forget to share it. Carbon Steel. Any metal that has iron as the main metal in its composition is considered to be ferrous. At present, the role of ferrous metals in the engineering Industries can be easily described as most dominating. The cylinder has an inner lining of Refractory Bricks which is provided with Tuyers near the bottom for injecting the supply of air blast. It is not suitable for shock and impact loads. You can find ferrous metals in large structures such as skyscrapers and bridges. The usual composition of Grey Cast Iron is: It is soft and ductile. Coke is used as fuel and limestone as a fluxing material. In the present, their role in the engineering industries can be easily described as “most dominating.”. 9. 2. Nickel is added to effect an increase in the hardness and resistance to wear. Ferrous metals are vulnerable to rust when exposed to moisture as they have a high carbon content. Recycling steel saves a lot of energy, natural resources and reduces harmful emissions to the atmosphere as a result of ore production. Most metals today are made up of several different elements. It is also used in buildings, railways, and marine industries. It is also called foundry pig. The alloy Cast Irons are used for gears, sprockets, wheels, I.C engine cylinders, piston, piston rings, crankcases, crankshafts, camshaft, brake drums and shoes, parts of grinding machines, etc. 3. List and Types of Ferrous Metals; Its properties, uses, etc. Some non-ferrous metals are made for cryogenic applications, others are made to withstand extremely high temperatures. Even though almost all this types of nonferrous metals are costly than ferrous metals, they are used in industrial application such as: roofing pipes, electrical and gutters. Pig Iron:. A silver-like colour 6. Ultimately, the metal deteriorates to the point of failure. Used in manufacturing of cisterns, sewer and drain pipes, manhole covers and fittings. Various types of ferrous metals and alloys are available in the market: Carbon steels are ferrous alloys that contain carbon and small levels of other alloying elements, such as manganese or aluminum. It is produced when the raw material is burnt at a very high temperature. Following are the common types of Cast Iron used in engineering materials. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. Ferrous metals are those which contain iron as their main constituent or base metal. The ferrous metals includes all the types of Iron, Steel, and their alloys. There are two processes for the manufacture of Wrought Iron: Its most important properties are mentioned below. It is hardest of all Cast Irons and is wear-resistant. It cannot be tempered or hardened like steel. Some internal recycling methods are obvious. It’s the most common non-ferrous (not containing iron) metal on the planet. properties. Due to these properties, Steel is used as a structural material in all types of situations. It is commonly used in castings, dies, molds, machine frames, and pipes, etc. It is used in Automobile industries for making rear-axle housing, steering-gear housing, hubs, and pedals, etc. Ferrous alloys or metals are metals that consist mostly of iron (Fe). Ferrous metals may include a lot of different alloying elements. While it doesn’t rust, it will oxidize. Low resistance to corrosion 5. It’s light red and turns greenish with oxidation. In case the metal contains iron, it is known as a ferrous metal, otherwise as non-ferrous metal. Cupola furnace is cylindrical in shape with an almost uniform diameter (about 1 meter) and a height of about 5 to 6 meters. It has a specific gravity of 7.5, and it has a melting point of 1250°C. Recycling - Recycling - Ferrous metals: Ferrous products (i.e., iron and steel) can be recycled by both internal and external methods. The alloying elements used are; nickel, chromium, molybdenum, and vanadium. Flux is the material which easily fuses and mixes with impurities to form a slag, which can be taken through the top of the furnace. Besides, Wrought Iron always contains a small proportion of slag in the silicate component. And carbon is included in these impurities, its proportion being generally less than 0.12 percent. Abrasive Definition and Types of Abrasives its Forms and Applications. Ferrous Metals. Those give ferrous steels mechanical properties that make them widely used in engineering. Metal plating uses chemical baths to coat or alter the surface of substrates with thin layers of metal such as zinc, nickel, cadmium, or chromium. A liquid slag forms when Limestone combines with earth matter. copper), low weight (e.g. It is a modified Grey Cast Iron. Density: The metal has a density of 7.8 gm/cm3 and a melting point of 1500 centigrade. The definition of a ferrous metal is any metal that contains iron; non-ferrous metals do not. Bronze, which is an alloy of copper and tin, was likely first used around 35,000 BC. It is used in flywheels and agricultural implements. The usual alloying elements are Nickel and Chromium. Ductile Cast Iron is produced by adding any one of the elements of magnesium, calcium, cerium, bismuth, zinc, cadmium, titanium, and boron into the molten Grey Cast Iron.
