Hastelloy B3 Flanges play various essential roles in pipe and tubing operations. This material offers some of the greatest strengths in the alloy flange family, including higher-than-average melting point and corrosion resistance. B3 Hastelloy Flanges are used widely for steam lines, sour gas pipelines, flare stacks, petroleum liquid lines and process piping systems. But that's not all - this flange can function as a seal to ensure tight connections between pipes. In addition, these joiners are suitable for significant temperature variations, while the chromium content helps protect against wear due to harsh environments. High nickel content also plays a part in protecting against oxidation and pitting by multiple corrosive agents. Such versatility makes Hastelloy B3 Flanges an ideal choice for many installations involving pressurized systems.

Hastelloy B3 Flanges are used in various industrial applications due to their corrosion and heat resistance. This is because they are composed of 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.
