Product Description
Bright Polished 17-4PH Stainless Steel Bar
17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This material maintains high strength up to approximately 600°F (316°C).
Standard: ASTM, GB, DIN, EN
Diameter: 8 - 450mm
Length: 6m per piece or custom cutting
Finishing: Black bar / Bright Bar
Material Properties
Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with copper and niobium additions. This grade combines high strength, hardness (up to 572°F / 300°C), and excellent corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).
Applications
  • Offshore applications (foils, helicopter deck platforms)
  • Food processing industry equipment
  • Pulp and paper manufacturing
  • Aerospace components (turbine blades)
  • High-performance mechanical components
  • Nuclear waste containment casks
  • Engine components and boat propeller shafts
  • Plastic molding dies, valves, and gears
