UNS N10276 pipe bend provides resistance to general corrosion like pitting and crevice corrosion
Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.
Compared to alloy B, alloy B-2 is less susceptible to weld zone corrosion in the as-welded condition. Controlling other alloying elements such as iron and chromium resolved potential issues with forming and shaping. Thus these Hastelloy B2 Flanges are considered to be well suited to be used for most chemical process applications in an as-welded condition. Due to lower carbon content in the alloy, there is reduced precipitation of carbides as well as other phases in the heat-affected weld zones, which in turn ensures uniform resistance to corrosion in the flange. Since the metal exhibits excellent resistance to pitting and stress related corrosion cracking, the Alloy B2 Blind Flange outperforms many conventional stainless steel grades, when used to block off a valve in piping systems. Stringent chemistry control in the production of alloy B-2 allows the alloy to be used in the welded condition, and it is less susceptible to stress corrosion cracking under many conditions. Care must be taken in selecting the right alloy for the desired application.
