Common elements that affect the performance of steel

The common elements that affect the performance of steel are determined by their quality and properties according to their needs. Different element contents and types should be matched according to different needs
（1） Carbon: The higher the carbon content, the higher the hardness of the steel, but its plasticity and toughness are poorer.
（2） Sulfur: It is a harmful impurity in steel. In Dongguan forming machine, steel with high sulfur content is prone to brittle cracking during high temperature pressure processing, commonly referred to as thermal brittleness.
（3） Manganese: It can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties.
（4） Silicon: It can improve the hardness of steel, but its plasticity and toughness decrease. Steel used for electrical purposes contains a certain amount of silicon, which can improve soft magnetic properties.
（5） Tungsten: can improve the red hardness and thermal strength of steel, and can also improve the wear resistance of steel.
（6） Copper: Its prominent role is to improve the atmospheric corrosion resistance of ordinary low alloy steel, especially when used in conjunction with phosphorus.
