Hastelloy C276 sheet is a premium nickel‑molybdenum‑chromium alloy with outstanding corrosion resistance across a wide range of aggressive environments, including reducing, oxidizing, and chlorinated media. Because of these properties, Hastelloy C276 sheet is widely used in chemical processing, pollution control, marine engineering, oil & gas, and power generation industries. Choosing a reliable supplier is crucial to ensure material quality, traceability, and certification support. In this article, we explore Hastelloy C276 sheet properties, applications, and top suppliers in the market.
What Is Hastelloy C276 Sheet?
Hastelloy C276 is a nickel‑based corrosion‑resistant alloy combining molybdenum, chromium, and iron. This unique chemistry gives exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in harsh environments such as sulfuric, phosphoric, and hydrochloric acids. The sheet form allows the material to be used for fabrications such as tanks, liners, cladding, and flanges where flat stock is needed for forming or welding.
