The relationship between chemical composition and stainless steel performance

1. Carbon C: It can increase the hardness and strength, if the content is too high, it will reduce its ductility and corrosion resistance.
2. Chromium Cr: It can increase corrosion resistance and oxidation resistance, refine the grain size, increase strength, hardness and wear resistance.
3. Nickel Ni: It can increase high temperature strength, corrosion resistance, and reduce the rate of cold work hardening.
4. Molybdenum Mo: Increases strength and has excellent corrosion resistance to oxides and seawater.
5. Copper Cu: It is beneficial to cold forming and reduces magnetic properties.
