Precipitation Hardening Stainless Steel Round Bar

High Strength 17-4PH Stainless Steel Bar

Corrosion Resistant UNS S17400 Round Bar

Product Description

17-4 PH (630) / UNS S17400 / DIN 1.4542 Stainless Steel Bright Round Bar

17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).

General Properties

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Applications & Standards

Applications	Standards
Offshore (foils, helicopter deck platforms) Food industry Pulp and paper industry Aerospace (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 risks, higher aging temperatures above 1022°F (550°C) are recommended. The alloy provides corrosion resistance in chemical, petroleum, paper, dairy, and food processing industries.
