Hastelloy C-276 material introduction
Hastelloy C-276 alloy belongs to the nickel-molybdenum-chromium-iron-tungsten nickel-based alloy. It is the most corrosion-resistant kind of modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts. It has good corrosion resistance at low and medium temperatures. Therefore, in the past 30 years, in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper, environmental protection and other industrial fields, it has been widely used. The various corrosion data of Hastelloy C-276 alloy is typical, but it cannot be used as a specification, especially in an unknown environment. The material must be selected after testing. There is not enough Cr in Hastelloy C-276 alloy to resist corrosion in a strong oxidizing environment, such as hot 1. The production of this alloy is mainly aimed at the chemical process environment, especially in the presence of mixed acids, such as the discharge pipe of the flue gas desulfurization system.
It has excellent resistance to stress corrosion cracking and good local corrosion resistance. It has satisfactory corrosion resistance in many chemical process media, including strong etched inorganic acid solutions, chlorine and various chloride-containing media, and dry Chlorine, formic acid and acetic acid, sea water and salt water, etc.
