Stainless Steel Flat Bar 17-4 PH Annealed Hot Rolled and Pickled

17-4PH, also known as UNS S17400, is a precipitation-hardening stainless steel that combines high strength, hardness, and excellent corrosion resistance. The "PH" stands for "precipitation hardening," a heat treatment process that increases the material's strength and hardness. In its annealed condition, 17-4PH stainless steel is relatively soft and ductile, making it easier to machine and form.
