Material Characteristics:
① High chromium molybdenum content, can withstand oxidation and non-oxidation acid, and has excellent resistance to pitting and crack erosion in the presence of chloride and other halides.For example, in many harsh corrosive environments, including sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, hypochlorite, [SCALE STEEL]wet chlorine, etc., it has good corrosion resistance to uniform corrosion, stress corrosion cracking, pitting and crevice corrosion;Strong resistance to sulfide stress cracking and stress corrosion cracking in acidic oilfield environment.
② Low carbon content can reduce the carbide precipitation during welding, so as to ensure the intergranular corrosion resistance in the heat-affected zone of welded joints.

Applications:
Because of its excellent overall corrosion resistance, C276 is generally considered to be a versatile corrosion resistant nickel-based alloy with [SCALE STEEL]wide applications in the chemical, petrochemical and petroleum industries.Applications include chemical applications for a variety of production purposes, power plant flue gas desulfurization (FGD) systems, and acid oil field environments.
