Main chemical components's roles:

  • Cr: Can significantly improve strength, hardness and wear resistance, oxidation resistance and corrosion resistance.

  • Ni:  Increases the strength of steel while maintaining good ductility and toughness.

  • P: Makes it easy to cut and is beneficial to improve the machinability of steel.

  • Mn: Can increase the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel

  • Si: Can increase the hardness of steel and improve the soft magnetic properties.
