Hastelloy B3 Flanges are flanges made from a nickel-molybdenum alloy called Hastelloy B3. This material is highly resistant to corrosion in various reducing environments. It is ideal for harsh industrial applications, such as chemical processing, pollution control, and pulp and paper production. Hastelloy B3 Flanges offer exceptional resistance to hydrochloric acid at all concentrations and temperatures, making them a popular choice for industries dealing with acid production and other corrosive substances.
Hastelloy B3 Price in India is Rs 4000/- (Per Kg)
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.
