High Hardness 17-4PH / 630 / S17400 Stainless Steel Round Bar
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 material maintains high strength up to approximately 600°F (316°C).
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 excellent corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Corrosion Resistance
17-4PH stainless steel offers superior corrosion resistance compared to standard hardenable stainless steels, comparable to Alloy 304 in most media. For optimal performance in chloride media, aging at 1022°F (550°C) is recommended, while 1094°F (590°C) is preferred for H2S environments.
Heat Treatment
Solution Treatment (Condition A): Heat to 1040°C for 0.5 hours, then air-cool to 30°C. Small sections may be oil quenched.
Age Hardening: Performed at low temperatures to achieve required mechanical properties. Typical conditions include H900 (482°C/1h), H925 (496°C/4h), H1025 (552°C/4h), H1075 (580°C/4h), H1100 (593°C/4h), and H1150 (621°C/4h).
Fabrication
Welding: All conventional methods can be used without pre-heating requirements.
Machining: Best performed in solution-treated condition with machining rates similar to grade 304 stainless steel.
