C276
Type Hastelloy C-276 alloy is one of the widely used nickel-molybdenum-chromium corrosion-resistant alloy grades. With its highly corrosion-resistant composition, it provides exceptional resistance to strong oxidizing and reducing chemicals, as well as to pitting and crevice corrosion. Grade Hastelloy C-276 is commonly applied in chemical, environmental, and marine industries, especially in harsh process environments containing chlorides and strong acids.
