Different elements of steel have different effects on steel

According to the needs to determine the quality and function of steel, different needs, to have different element content.

Carbon: The higher the content, the higher the hardness of the steel, but the worse its plasticity and durability, the higher the hardness of the steel.

Sulfur: harmful impurities in steel, high sulfur steel in high temperature pressure processing, simple brittle, generally known as hot brittleness.

Phosphorus: can significantly reduce the plasticity and resistance of steel, especially at low temperatures. This phenomenon is called cold brittleness. In excellent steel, sulfur and phosphorus should be strictly controlled. But on the other hand, low carbon steel contains high sulfur and phosphorus, which can make it brittle and help improve the cuttability of steel.

Manganese: High alloy steel (high manganese steel) has excellent wear resistance and other physical functions, which can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel.

Silicon: It can improve the hardness of steel, but the plasticity and durability are reduced. Electrical steel contains a certain amount of silicon, which can improve the soft magnetic function.

Tungsten: can improve the red hardness and hot strength of steel, improve the wear resistance of steel.

Chromium: can improve the hardenability and wear resistance of steel, improve the corrosion resistance and oxidation resistance of steel.
