It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.
The machinability of grade 202 stainless steel produces long, gummy chips. Machining can also be performed in the annealed condition. For heat treatment, the material has to be soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for full martensite transformation. The material can be welded by common fusion and resistance methods; however, this steel should not be joined using oxyacetylene welding method. The recommended filler metal is AWS E/ER630. Forging can be done by pre-soaking for 1 h at 1177°C (2150°F). Forging below 1010°C (1850°F) is not advisable.
