Heat resisting AISI 422 stainless is also referred to Carpenter 636, AISI 616, UNS S42200, equivalent to german
grade EN 1.4935, DIN X20CrMoWV12-1 stainless. It is a modification type of AISI 420, with addition
of nickel, molybdenum, tungsten and vanadium to improve the elevated temperature strength
and resistance to stress corrosion cracking.
AISI 422 is a hardenable martensitic stainless steel which is being widely used for high temperature
up to 1200F. It has the excellent creep rupture properities in the range of 600/1200F and is capable
of being heat treated to various high strength levels depending on section, forms, and application involved.
Typical applications:
- Compressor and turbine blades ( aircraft, gas or steam turbines )
- Compressor and turbine wheels
- Rotors
- High temperature bolting
- Valve trim and other valve applications
- Structural components for aircraft and missile applications
