Application areas

Alloy C276 can be used in the most severe environments such as chemical and petrochemical processing involving bleach, pollution control, pulp and paper production, industrial and municipal waste treatment, pharmaceutical and food processing equipment, and process plant involved in the recovery of sour natural gas. Alloy C276 is ideal for use in evaporators, heat exchangers, sulphuric acid filters and reactors, and process plant handling acid catalysts.

Corrosion properties

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

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.
