The Hastelloy C276 Flanges are the most used grade of flanges from the wide range of Hastelloy alloy flanges. They offer superlative resistance against corrosion in an array of severe environments. The high Nickel and Molybdenum content in these Flanges makes them resistant to pitting and crevice corrosion, especially in reducing environments. They contain low amounts of Carbon, minimizing the grain-boundary carbide precipitation which maintains the corrosion resistivity of these Flanges. The Hastelloy C276 Flanges are one of the very few flanges that are suitable for applications in corrosive environments that contain agents like wet chlorine gas, hypochlorite and chlorine dioxide.
The Hastelloy C276 Flanges are considered as one of the most versatile corrosion resistant Flanges available. They offer high resistivity against formic and acetic acids, seawater, brine, hypochlorite and chlorine dioxide solutions. They are also resistant to environments that contain hot contaminated or
