17-4 PH is a martensitic precipitation hardening stainless steel with additions of copper (Cu), niobium (Nb) and tantalum (Ta). The grade combines high strength and hardness values with moderate corrosion resistance. Different heat treatment temperatures can optimize mechanical properties, e.g. yield strength at 1100 – 1300MPa. Our stock material is double aged at 620°C (1150°F) – defined as H1150D.
