27 sie 2023 · 17-4PH H900 Heat Treatment: Heat treatment plays a crucial role in enhancing the properties of 17-4PH H900. The alloy is typically solution annealed at temperatures ranging from 1900°F to 1950°F (1040°C to 1065°C), followed by air cooling or rapid quenching.
14 sty 2024 · Abstract. Post-fabrication heat treatment (PFHT) is one of the most applied strategies for achieving the desired microstructure and mechanical resistance on additive manufactured components because of the non-equilibrium microstructural state of the material in the as-built condition.
24 sie 2006 · The correct process for heat treating condition a 17-4 to h900 is to heat to 900°f soak for 1 hour then cool.
17-4 PH is a martensitic precipitation age-hardening stainless steel with high strength and hardness, and good corrosion resistance. 17-4 PH is used in a variety of applications including medical instruments, chemical processing equipment, gears, nuclear reactor components, and jet engine parts.
Processing – Hot Forming: To 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.
