Product Description
ASTM B564 N10276 Hastelloy Alloy is a nickel chromium molybdenum alloy containing tungsten, with extremely low silicon carbon content, and is considered a versatile corrosion-resistant alloy. This alloy has the following characteristics: ① It has excellent corrosion resistance to most corrosive media in both oxidation and reduction atmospheres. ② Has excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, while tungsten further enhances the corrosion resistance. Meanwhile, C-276 alloy is one of the few materials that is resistant to corrosion from humid chlorine gas, hypochlorite, and chlorine dioxide solutions, and has significant corrosion resistance to high concentration chloride solutions such as iron chloride and copper chloride. Suitable for sulfuric acid solutions of various concentrations, it is one of the few materials that can be applied to hot concentrated sulfuric acid solutions.
ASTM B564 N10276 Hastelloy Alloy (UNS N10276/W. Nr. 2.4819) is renowned for its corrosion resistance in various corrosive media. The high molybdenum content endows it with the ability to resist localized corrosion such as pitting corrosion. Low carbon can minimize the precipitation of carbides during the welding process to maintain the resistance of the heat affected zone of the welded joint to intergranular corrosion.
