Product Overview –Hastelloy C276 Pipes
Hastelloy C276 Pipes, are among the world's most versatile corrosion-resistant nickel alloy pipes, designed for applications involving aggressive chemicals, high temperatures, and harsh industrial environments. Manufactured from a nickel-molybdenum-chromium alloy with tungsten, Hastelloy C276 provides exceptional resistance against oxidizing and reducing acids, wet chlorine, chlorine dioxide, ferric chloride, sulfuric acid, hydrochloric acid, phosphoric acid, seawater, and numerous corrosive process chemicals.
One of the biggest advantages of Hastelloy C276 is its ability to resist pitting corrosion, crevice corrosion, chloride stress corrosion cracking (SCC), and localized attack even in extremely aggressive environments where conventional stainless steels, duplex stainless steels, and many nickel alloys fail. Because of these properties, Hastelloy C276 has become one of the most trusted materials in chemical processing, offshore oil & gas, marine engineering, pharmaceutical manufacturing, flue gas desulfurization systems, pollution control equipment, pulp & paper plants, fertilizer plants, and power generation industries.
