Nickel Alloy Hastelloy C-276 hastelloy c4 hastelloy b2 hastelloy b3 Pipe Tubes Manufacturer

Hastelloy C-276: Highly corrosion-resistant nickel-based alloy. Ideal for harsh environments, including strong acids, chlorine, and seawater. Resists pitting, crevice corrosion, and stress corrosion cracking. Widely used in chemicals, petrochemicals, and marine industries. Available in various forms. Trusted for durability and reliability.

Product Description:
C276 alloy is suitable for many kinds of chemical process industry containing oxidizing medium and reducing agent. High content of molybdenum and chromium makes it resistant to chloride corrosion, and high content of tungsten makes it better resistant to corrosion. C276 alloy is one of the few materials resistant to most chlorine, hypochlorite and chlorine dioxide corrosion, the alloy has outstanding resistance to high concentrations of chlorate (ferric chloride and copper chloride).

Product features:
1. In oxidation and reduction state, excellent corrosion resistance to most corrosive media.
2. Excellent resistance to point corrosion, crack corrosion and stress corrosion cracking.
