SAE J467 17-4PH Super Alloy Semi Austenitic Precipitation and Transformation Hardening Stainless Steel Round Bar
17-4PH is a chromium-nickel-copper precipitation hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance.

1.4542, X5CrNiCuNb14-5 630,17-4ph
Process: Cold drawn, hot rolled, forged
Diameter: 15-150mm, 160-300mm, 310mm-500mm
Length: max 8000mm
Surface:Black, turned, ground, peeled, polished
Tolerance: ISO h8, h9, h10, h11, h12
Solution treatment (Condition A):Grade 17-4PH stainless steels are heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections of these grades can be oil quenched.
Cold Working: Alloy 17-4PH has limited cold forming properties. Cold forming can only be undertaken on plates in the fully annealed condition. Stress corrosion resistance is enhanced by re-aging at the precipitation hardening temperature after cold working.
Hot Forming:Heat uniformly at 1742–2192°F (950–1200°C). A full solution anneal, cooling lower than 76°F (25°C) and aging at the required temperature must occur after
hot forming. The post forming heat treatment should be a function of the desired mechanical properties.
Annealing: stainless steel is annealed at 843-871°C (1550-1600°F) followed by slowly cooling in the furnace.
Hardening:17-4PH stainless steels are age-hardened at low temperatures to achieve the required mechanical properties. During the process, superficial discoloration occurs followed by shrinkage at 0.10% for condition H1150, and 0.05% for condition H900.
