Material Description
17-4PH Precipitation Hardening (Type 630) 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).
General Properties
Alloy 17-4 PH 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). Not recommended for use above 572°F (300°C) or at very low temperatures.
Applications & Standards
Applications: Offshore industries, food processing, pulp and paper, aerospace, mechanical components, nuclear waste casks
Standards: ASTM A693 grade 630, UNS S17400, EURONORM 1.4542, AFNOR Z5 CNU 17-4PH, DIN 1.4542
