Hastelloy C-276 (UNS N10276) Seamless & Welded Nickel Alloy Pipe Supplier

Hastelloy C-276 (UNS N10276) Nickel Alloy Pipe

Hastelloy C-276 pipe is a nickel-molybdenum-chromium alloy engineered for superior corrosion resistance in extremely aggressive environments. It provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in high chloride and strong acid conditions. This makes it one of the most versatile and widely used nickel alloys in chemical processing industries.

Key Features

• ✔ Exceptional resistance to localized corrosion
• ✔ Excellent performance in oxidizing and reducing acids
• ✔ High resistance to chloride-induced stress corrosion cracking
• ✔ Good weldability without post-weld heat treatment
• ✔ Reliable strength across a wide temperature range
