Hastelloy Alloys And Its Composition

Chemical composition of Hastelloy c276

Hastelloy C276 is a wrought nickel-chromium-molybdenum alloy that is widely regarded as the most versatile corrosion-resistant alloy available. This alloy resists the formation of grain boundary precipitates in the weld heat-affected zone, making it suitable for most chemical process applications as welded. Alloy C-276 is highly resistant to a wide range of chemical environments.
