Description
Hastelloy B2 Flanges
Hastelloy B2 Flanges is manufactured using the hastelloy grade B2 alloy, consisting of nickel and molybdenum. This composition makes it ideal for severe reducing conditions when compared to conventional grades due to its inclusion of iron, carbon, and silicon. Renowned for superb corrosion resistance in environments with acids such as sulfuric acid and hydrofluoric acid that are non-oxidizing, Hastelloy B2 flanges are utilized extensively in chemical processing sectors including pulp & paper industry as well as petrochemicals.
Additionally notable features include robust strength across a broad temperature spectrum along with resilience against hydrogen embrittlement, thus also finding extensive application in marine engineering projects alongside oil & gas companies or desalination facilities among other industries demanding reliability under elevated temperatures or generalized corrosive exposure scenarios.
SASA FLANGE offers extensive selection of Hastelloy B2 Flanges including slip-on flanges, weld necks, socket weld options, blind flanges configurations, lap joint types, threaded types, long weld neck options, available in ANSI/ASME, DIN, JIS standards, and we insist on reliable quality, full material traceability, and competitive pricing to meet the demanding needs of global clients.
