General Information
Stainless Steel Alloy 422 is mainly used for manufacturing of buckets and blades for steam turbines, but also in the aerospace industry for manufacturing of high temperature bolting, valves and valve trim. Other less common applications of Stainless Steel 422 are in refineries, thermal pipe plants, pharmaceutical industry, oil refineries, textile industries, nuclear plants, chemical industry, etc.
Stainless Steel 422 is hardenable high-alloy Stainless Steel with a martensitic crystal structure and good resistance to corrosion. It is mainly used for manufacturing of parts that are subjected to high temperatures of up to 1200° F (649° C). With the right heat treatment, parts made of this steel can also have excellent mechanical properties depending on section, form, and application involved.

Physical Properties
Physical Properties of 422 Stainless Steel
| Density | Heat Treatment | Hardening |
| 0.280 lb/cubic inch | Heat treatment is sensitive as the alloy is very susceptible to cracking | In the annealed condition, typical hardness is Rc 21/25. In the quenched and tempered condition, hardness is typically Rc 45/50. |
