17-4 PH Stainless Steel (AISI 630) 17-4 PH is a precipitation hardening, martensitic stainless steel (17Cr-4Ni). It is noted for its high strength and hardness, excellent corrosion resistance and easy heat treatment. 17-4PH is usually machined to finished dimension in the solution heat treated and then strengthened by age hardening via the low temperature treatment process described below. 17-4 PH is magnetic in both the solution treated and age hardened conditions. TYPICAL CHEMISTRY: C 0.07 max. Mn 1.00 […]
