Product Description
Grade 630 Stainless Steel Round Bar
Diameter Range: 10 - 300mm SS Bars
Product Overview
17-4PH Stainless Steel (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This grade maintains high strength up to approximately 600°F (316°C).
Product Specifications
Standard: ASTM, GB, DIN, EN
Diameter: 8 - 450mm
Length: 6m per piece or custom cutting
Finishing: Black Bar / Bright Bar
Available Grades
Main grades include: 201, 301, 303Cu, 304, 304L, 309S, 310S, 316L, 316Ti, 317L, 318, 321, 347, 410, 420, 430, 431, 440a/b/c, 904L, 2205, 2507, Hastelloy C276/C4/C22, Inconel 600/625, Incoloy 800/825/825H, and others.
Material Properties
Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with copper and niobium additions. It combines high strength, hardness (up to 572°F/300°C), and corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

  • Pulp and paper industry
  • Aerospace components (turbine blades)
  • Mechanical components
  • Nuclear waste casks
  • Engine components
  • Boat propeller shafts
  • Plastic molding dies
  • Valves and gears
Heat Treatment
Solution treatment (Condition A): Heated at 1040°C for 0.5 hours, then air-cooled to 30°C. Small sections can be oil quenched.
Hardening: Age-hardened at low temperatures to achieve required mechanical properties. Superficial discoloration and shrinkage occur during the process.
Additional Services
We provide cutting, surface polishing, and heat treatment services. Our brands include Walsin, BAOSTEEL, TISCO, and QINGSHAN.
