APPLICATIONS OF STAINLESS 422
Buckets and blades in compressors and steam turbines, forged high-temperature bolting, compressor and turbine wheels, valves and valve trim and aircraft parts
FORGING STAINLESS 422
Large sections should be preheated to 1200/1400ºF (650/760ºC), then to 1900/2150ºF (1040/1175ºC). Forgings should be slow cooled and annealed or tempered as soon as possible after reaching room temperature.
Hardening should not be attempted without an inter anneal or preheat in the range 1200/1400ºF (650/760ºC.)
