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).
