X46CrS13
1.4035Free-cutting high-carbon martensitic stainless steel. Sulfur-enhanced variant of X46Cr13 (1.4034) for automated production of knife blades and cutlery. Combines the high hardness of X46Cr13 (up to 54 HRC) with excellent machinability for mass production on automatic lathes and CNC machines. Used for industrially manufactured knife blades, scissors, and cutting tools.
