Cr:significantly improve the strength, hardness and wear resistance, but also reduce the plasticity and toughness of steel. Improve the oxidation resistance and corrosion resistance.

Mo: grain refining of steel, improve the hardenability and heat resistance, sufficient strength and creep resistance at high temperature. Keep on tool steel can increase the red hardness of alloy steel. Inhibition of temper brittleness.

Mn: to improve the toughness, strength, hardness and wear resistance, wear resistance, improve the steel hardened steel, improve the heat treatment performance of the steel. Manganese increased, reduce the corrosion resistance, welding performance. Manganese is the weak carbide forming element.
