What is the difference between carbon steel and cast iron and pig iron?
Carbon steel mainly refers to a carbon alloy whose carbon content is less than 2.11%. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, also called carbon steel, refers to an iron carbon alloy with a carbon content of less than 2.11% Wc.Iron carbon alloy containing more than 2% carbon in iron.Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2%~4.3%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products.
Cast iron is commonly called "pig iron"". Is a carbon alloy containing more than 2% carbon. Industrial cast iron generally contains carbon from 2% to 4%. Carbon is often found in graphite form in cast iron and sometimes in cementite form. In addition to carbon, the cast iron also contains 1% to 3% silicon, as well as manganese, phosphorus, sulfur and other elements. The mechanical properties of cast iron are hard and brittle.
Known as the "iron carbon steel". Refers to the carbon content of less than 2%, and a small amount of silicon, manganese and phosphorus, sulfur and other impurities of iron carbon alloy. Carbon steels used in industry generally do not contain carbon content of more than 1.4%. This is because the carbon content exceeds this amount, the steel showed a large hard brittle, and processing difficulties, loss of production and use value. Carbon steel according to its different quality can be divided into ordinary carbon structural steel and high-quality carbon structural steel two categories. The quality carbon structural steel stipulates that the allowable content of sulfur and phosphorus is lower than that of ordinary carbon steel, so the comprehensive mechanical performance is better than that of plain carbon steel.
