Corrosion resistance and main use environment:

Hastelloy C-276 is a nickel-chromium-molybdenum alloy containing tungsten. It has a very low silicon-carbon content and is considered a universal anti-corrosion alloy. The alloy has the following characteristics: ①It has excellent corrosion resistance to most corrosive media in both oxidation and reduction atmospheres. ②It has excellent resistance to pitting, crevice corrosion and stress corrosion. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 alloy is one of the only materials that are resistant to corrosion by humid chlorine, hypochlorite and chlorine dioxide solutions, and has significant effects on high-concentration chloride solutions such as ferric chloride and copper chloride. Corrosion resistance. It is suitable for sulfuric acid solutions of various concentrations and is one of the few materials that can be applied to hot concentrated sulfuric acid solutions.
