Composition: 7CR17 and 3CR13 are both stainless steels made of carbon, chromium, and nickel—however, the key difference lies in their composition. 7CR17 contains 0.75% carbon, 17% chromium, and 1% nickel, while 3CR13 contains 0.3% carbon, 13% chromium, and 1% nickel. This means that 7CR17 is slightly harder and stronger …
