CPM S35VN is a high-alloy martensitic stainless steel designed to offer improved wear resistance and toughness over other steels, while still maintaining its corrosion resistance. The addition of niobium (as Niobium Carbide) gives the steel greater hardness and wear resistance, while vanadium carbides help to improve toughness. CPM S35VN also has a higher carbon content than most stainless steels, which helps to keep the edge sharp for longer periods of time.
