Description
Both are martensitic stainless steel, as you can see from the table, 2Cr13 vs 3Cr13 have only different carbon contents in the chemical composition. The strength and hardness of steel mainly depend on the carbon content. The higher the carbon content, the greater the strength, but the lower the corrosion resistance. The main effect of chromium is to improve the corrosion resistance. 2Cr13 vs 3Cr13 have little difference in mechanical properties such as yield strength, tensile strength, and annealing hardness. After heat treatment, 3Cr13 is higher in hardness than 2Cr13, but the corrosion resistance is worse than 2Cr13.
