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.
