Discover the Power of Hastelloy C 276 for Your Next Project
Durability and Versatility in One Alloy: Hastelloy C 276
Hastelloy C 276 is a nickel-molybdenum-chromium alloy that was developed by Haynes International in the early 1960s. It is part of the Hastelloy family of alloys, which are known for their resistance to corrosion and their ability to maintain their mechanical properties even at high temperatures.
It is composed of approximately 54% nickel, 16% chromium, 16% molybdenum, 5.5% iron, and small amounts of other elements such as tungsten and cobalt. Its high nickel content makes it highly resistant to corrosion by a wide range of chemicals, including chlorides, sulfuric acid, hydrochloric acid, and phosphoric acid.
One of the key benefits of Hastelloy C276 is its excellent resistance to localized corrosion, such as pitting and crevice corrosion. This is due to the alloy’s ability to form a protective oxide layer on its surface when exposed to corrosive environments. Additionally, Hastelloy C276 has good mechanical properties, including high strength and ductility, which make it suitable for use in a variety of applications.
Hastelloy C276 is used in a wide range of industries, including chemical processing, petrochemicals, pharmaceuticals, pulp and paper, and waste treatment. Its versatility and durability make it a popular choice for critical applications such as pressure vessels, heat exchangers, and reactors.
