What is general carbon steel

Mainly refers to the mechanical properties of steel depends on the carbon content, and generally do not add a large number of alloying elements of steel, sometimes also known as carbon steel or carbon steel.

Carbon steel, also known as carbon steel, is an iron-carbon alloy with less than 2% WC. Carbon steel in addition to carbon generally contains a small amount of silicon, manganese, sulfur, phosphorus according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free cutting structural steel three categories. Carbon structure steel is divided into building structure steel and machine manufacturing structure steel according to the carbon content can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (wc0.25% -- 0.6%) and high carbon steel (WC>). According to phosphorus, sulfur content can be divided into ordinary carbon steel (containing phosphorus, sulfur higher), high quality carbon steel (containing phosphorus, sulfur lower) and high quality steel (containing phosphorus, sulfur lower) in general carbon steel with a higher carbon content, the higher the hardness, the higher the strength, but the lower the plasticity.
