Alloy steel contains more other elements than carbon steel
Alloy steel means that in addition to silicon and manganese as alloying elements or deoxidizing elements, the steel also contains other alloying elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements) etc.), and some also contain certain non-metallic elements (such as boron, nitrogen, etc.). According to the content of alloying elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel.
Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a large amount of alloying elements, and is sometimes called plain carbon steel or carbon steel.
Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of elements such as silicon, manganese, sulfur, and phosphorus. According to the application, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is divided into building structural steel and machine-made structural steel. According to the carbon content, carbon steel can be divided into low-carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%--0.6%) And high carbon steel (WC>0.6%) According to the phosphorus and sulfur content, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and High-grade high-quality steel (lower phosphorus and sulfur content) Generally, the higher the carbon content in carbon steel, the higher the hardness and strength, but the lower the plasticity.
