Hastelloy C-276 is one kind of tungsten-containing nickel-chrome-molybdenum alloy, which is considered to be a versatile corrosion resistant(mainly to wet chlorine, various oxidizing chlorides, chloride salt solution, sulfuric acid and oxidizing salts) alloy due to its extremely low silicon carbon content. And in low temperature and medium temperature hydrochloric acid it also have good corrosion resistance. Therefore, in the past 30 years, Hastelloy C-276 alloy is widely used in the harsh corrosive environments such as chemical, petrochemical, flue gas desulfurization, pulp and paper, environmental protection and other industrial fields. Hot forming of Hastelloy C-276 alloy is performed by immediate annealing at 1150℃ and rapid cooling with water. Cold deformation of Hastelloy C-276 alloy can increase its strength. Hastelloy C-276 alloys have similar formability to ordinary austenitic stainless steels. Meanwhile, due to its greater strength than ordinary austenitic stainless steel, there will be more stress during the cold forming process. In addition, the work hardening rate of this material is much faster than that of ordinary stainless steel, so in the extensive cold forming process, it is necessary to take mid-annealing treatment.
Hastelloy C-276's Characteristics:
1.Excellent corrosion resistance to most corrosive medias in oxidation and reduction atmosphere state.
2.Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion.
High content of Mo and Cr improves the alloy's resistance to chloride ion corrosion, meanwhile 'W' element strongs the corrosion resistance of Hastelloy C-276. After that, Hastelloy C-276 alloy is one of the unique several materials which resistant to moisture chlorine, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high concentration of chloride salt solutions such as ferric chloride and copper chloride. Besides, this alloy is applicable to sulfuric acid solution with various concentrations and is also one of the few materials that can be applied to hot concentrated sulfuric acid solution.
