17-4 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 is a precipitation hardening martensitic stainless steel with copper and niobium/columbium additions. This grade combines high strength, hardness (up to 572°F / 300°C), and excellent corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).
Alloy 17-4 PH offers superior corrosion resistance compared to standard hardenable stainless steels and is comparable to Alloy 304 in most media. For applications with potential stress corrosion cracking risks, higher aging temperatures above 1022°F (550°C) are recommended. The alloy provides excellent resistance in chemical, petroleum, paper, dairy, and food processing industries.

Processing Characteristics
Heat Treatment
Grade 630 stainless steels undergo solution treatment at 1040°C for 0.5 hours followed by air cooling. Age hardening at low temperatures achieves required mechanical properties with minimal distortion, making it ideal for long shafts and precision components.
Welding & Machining
This grade can be welded using all conventional methods without pre-heating requirements. Machining is most effective in the solution-treated condition, with machining rates comparable to grade 304 stainless steel.
Primary Applications
Engine components
High-strength boat propeller shafts
Plastic molding dies
Valves and gears
Aerospace components
Nuclear industry applications
