C276 is resistant to pitting, stress corrosion cracking, and crevice corrosion in a wide range of chemical environments, particularly in chloride gas, hypochlorite and chlorine dioxide solutions. Meanwhile the chromium content adds resistance to oxidizing media, such as ferric and cupric chlorides. To complete the overall corrosion resisting properties, tungsten is present to provide additional general resistance in a wide range of severe environments.
Welding properties are good, with the low carbon content minimizing carbide / grain boundary precipitation during welding to maintain corrosion resistance in the welded finished condition.
