OVERVIEW
440 STAINLESS STEEL
440 stainless steel comes from the martensitic family of steels, which are primarily valued for their strength. 440 steel is unique not only as the strongest stainless steel available, but as one of the few varieties that can be heat treated through annealing, hardening, and stress relieving processes.
