Applications of Hastelloy B3 Flanges:

Hastelloy B3 Flanges are used in various industrial applications due to their corrosion and heat resistance. This is because they comprise nickel, chromium, molybdenum, tungsten, cobalt and up to 12% iron. The high levels of molybdenum give it excellent oxidation properties, while the chromium contributes to its enhanced corrosion resistance. The presence of tungsten boosts its toughness against elevated temperatures, while cobalt helps with forming complex intermetallic phases, which improves its service performance in harsh conditions. The addition of iron contributes to building a solid alloying structure, allowing Hastelloy B3 Flanges to maintain their high strength in corrosive environments.
