X90CrMoV18
1.4112High-carbon martensitic stainless steel — 0.9% C + 18% Cr. Achieves HRC 58-60 after hardening — among the hardest stainless steels. Better corrosion resistance than 440C (1.4125) due to higher Cr (17-19% vs 16-18%). THE premium European cutlery/surgical instrument stainless. Used for kitchen knives, surgical scalpels, razor blades, ball bearings in corrosive environments, and valve seats.
