Does pig iron belong to alloy?
The steel system is made from pig iron and has higher mechanical strength and toughness. It also has special properties such as heat resistance, corrosion resistance and wear resistanceThe difference between iron and steel:Iron is rich in natural reserves, accounting for 5% of the total content of the earth's crust, and occupies fourth of the earth's material. Iron is very active and easily combined with other substancesHabits often said that the steel is steel and iron in general. There is a difference between steel and iron, the iron and steel, mainly by two elements, namely iron and carbon, elemental carbon and iron in general form compounds, called the iron carbon alloy. Influence of carbon content on the properties of the maximum number of iron and steel, carbon content increased to a certain extent will cause qualitative changes. Iron atoms from the material called iron, iron impurity is less. The carbon content is the main difference between how many standard steel. Pig iron carbon content of greater than 2%; carbon steel carbon content less than 2.0%. high iron, hard and brittle, almost no plastic steel. Not only has good plasticity, and steel products with high strength, good toughness, high temperature resistance, corrosion resistance, impact resistance, easy processing, easy to refine the application of excellent physical and chemical properties, so it is widely used.1, other names of pig iron, commonly known as: definitionPig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace products. According to the different forms of carbon in pig iron, and can be divided into pig iron, cast iron and steel ball ductile cast iron and other types.Pig iron performance: pig iron is hard, wear-resisting, casting good, but pig iron is crisp, can not forge
Because the graphite is soft, with lubrication, so the cast iron has good abrasion resistance, cutting and casting performance. But it is not anti digital strength, it is not only used for producing all kinds of forging, casting, such as a variety of machine tool bed casting base, iron pipe. Ductile iron to carbon exists in spherical graphite morphology the mechanical properties of gray iron, far and close to steel, it has excellent casting, machining and wear resistance, has a certain flexibility, widely used in the manufacture of gear, crankshaft, piston and a variety of advanced casting machine parts. In addition to silicon, manganese, nickel or other elements of a particularly high amount of iron, alloy such as iron, ferrosilicon, ferromanganese, commonly used as raw material for steelmaking. In certain alloy steel-making pig iron, steel can improve performance.
No, it's iron containing impuritiesGenerally refers to the iron alloy carbon content in 2~4.3% iron. Also called iron. Iron in addition to carbon, silicon, manganese and also contains a small amount of sulfur and phosphorus, it can cast NONMALLEABLE. According to the different forms of carbon in pig iron, and can be divided into several kinds of iron and iron for steelmaking, casting ductile iron. Steel and iron in carbon mainly exists in the form of iron carbide, the white section, usually called white iron.
