High-Strength 17-4PH Stainless Steel Bar (Grade 630) - Precipitation Hardened

17-4PH stainless steel provides exceptional corrosion resistance, strong mechanical properties, and excellent heat treatability. It features superior resistance to chloride stress corrosion cracking in chloride environments. Its composition—iron, chromium, nickel, copper, and molybdenum, plus minor carbon and niobium—delivers reliable performance and stability in high-temperature and highly corrosive conditions.

Key Properties
  • High Strength: Achieves ~1100 MPa tensile strength through heat treatment (e.g., H1150 condition: solution treatment + low-temperature aging).
  • Corrosion Resistance: Superior to many stainless steels, particularly in demanding chemical and climatic environments.
  • Heat Treatability: Adjusts performance via solution treatment and aging for enhanced strength or corrosion resistance.
  • Grindability: Maintains good surface finish post-heat treatment for precision applications.
  • Weldability: Achieves good results with proper heat treatment control and welding procedures.
Applications

Widely used in aerospace, petrochemical, medical devices, and other demanding fields due to its optimal balance of strength, hardness, corrosion resistance, and heat treatability.
