202 stainless steel is a type of Cr-Ni-Mn stainless steel with similar properties to 302 stainless steel.
202 stainless steel
202 stainless steel is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness and strength.
202 stainless steel machinability produces long, gummy chips. Machining can also be performed in the annealed condition. For heat treatment, 202 stainless steel has to be soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for full martensite transformation. 202 stainless steel can be welded by common fusion and resistance methods; however, 202 stainless 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.
