Product Overview
Hastelloy C276 is one of the most versatile nickel alloys available for industrial applications. It is specially designed to resist pitting corrosion, crevice corrosion, stress corrosion cracking, and localized attack in aggressive chemical environments. Due to its low carbon content, the alloy minimizes carbide precipitation during welding, allowing fabricated equipment to maintain its corrosion resistance even after welding operations.
The alloy performs exceptionally well in hydrochloric acid, sulfuric acid, phosphoric acid, chlorine gas, ferric chloride, seawater, and numerous oxidizing and reducing chemicals. These characteristics make Hastelloy C276 flanges suitable for high-pressure piping systems where safety, durability, and reliability are essential.
Material Composition
The superior corrosion resistance of Hastelloy C276 is achieved through its balanced chemical composition.
