It is a martensitic stainless steel with high hardenability (58 – 60 Rc).
It is a martensitic stainless steel with high hardenability (58 – 60 Rc).
Air hardening should be preferred for parts with complex shapes. Can be polished, usually not welded.
Wear resistance is also high.
Knives and cutting tools, rollers, punch discs, which should be stainless,
