GRADE STAINLESS STEEL 440C | AISI 440C | UNS S44004
Stainless Steel 440C is a high carbon chromium stainless steel. It has great corrosion resistance when hardened. It shows great resistance to wear and abrasion. It is magnetic in all conditions and yields the highest hardnesses of hardenable stainless steels.
440C Bearing Quality (BQ) is a Martensitic stainless steel with high strength, corrosion resistance and hardness obtained by low temperature heat treatment.
