The density of carbon steel is 7,81 to 7,85 tons per cubic meter. Carbon steel is a kind of steel that generally does not add a lot of alloy elements, sometimes called plain carbon steel or carbon steel. Carbon steel is called carbon steel because its carbon content is less than 2%, and it generally contains a small amount of silicon, manganese, sulfur, phosphorus, etc. in addition to carbon. Carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel.
The density of alloy steel is 7, 82 tons per cubic meter. Alloy steel refers to steel containing other alloy elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements), as well as some non-metallic elements (such as boron, nitrogen, etc.) in addition to silicon and manganese as alloying or deoxidizing elements. Due to the different kinds and quantities of alloy elements contained in the alloy steel and the adoption of appropriate process measures, it can have high strength, toughness, hardenability, wear resistance, corrosion resistance, low temperature resistance, heat resistance, heat strength, red hardness and other special properties.
