بیشتر17-7 PH® is a precipitation hardened (PH) stainless steel. It has the same easy-to-work characteristics of the 300 series alloys, yet it is capable of being hardened by a simple heat treatment. It has higher tensile strength/hardness compared to the 300 series when cold worked, and much higher tensile strength/hardness when heat treated.
بیشترDescription. 17-7 PH is a precipitation-hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications.
بیشترAging. Stainless steel grade 17-7 PH is solution annealed at 1177°C (2150°F) for 4 h and air cooled. Same step is performed at 1079°C (1975°F) for 4h and air cooled, then at 843°C (1550°F) for 24h and air cooled, and at 760°C (1400°F) for 16h and air cooled. This completed the precipitation hardening process.
بیشترTo forge, heat uniformly to 2150 / 2200°F and hold for half hour per inch. Preferred temperature range for hot forming is at 650-900°F, while the steel is still austenitic. To ensure the best condition for the hardening operations, the forgings must be re-heat treated at 1875-1925°F. Cool forgings to below 90°F to ensure grain refinement.
