Type 630 (17-4PH) Stainless Steel Round Bar

17-4 Precipitation Hardening (Type 630/UNS S17400) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).

Material Overview

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 corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Applications & Standards

Applications	Standards
Offshore equipment (foils, helicopter deck platforms) Food processing industry Pulp and paper industry Aerospace components (turbine blades) Mechanical components Nuclear waste casks	ASTM A693 grade 630 (AMS 5604B) UNS S17400 EURONORM 1.4542 X5CrNiCuNb 16-4 AFNOR Z5 CNU 17-4PH DIN 1.4542

Corrosion Resistance

Alloy 17-4 PH withstands corrosive attacks better than standard hardenable stainless steels and is comparable to Alloy 304 in most media. For stress corrosion cracking prevention, higher aging temperatures above 1022°F (550°C) are recommended. The alloy provides corrosion resistance in chemical, petroleum, paper, dairy, and food processing industries equivalent to 304L grade.
