The types ofHastelloy c22/C276 Flangesthat we consider to provide are including forged flanges, ring type joint flanges, slip-on raised face flanges, reducing flanges, blind raised face flanges, spectacle blind flanges, weld neck raised face flanges, orifice flanges, socket weld raised face flanges, threaded flanges, screwed flanges. More types of flanges available are groove & tongue flanges, JIS STD flanges, plate flanges, DIN flanges, flat face flanges, and BS 4054 flanges, BS 10 flanges, EN 1092-1 flanges, and ASME / ANSI / ASA B16.5 flanges.
Hastelloy c22 is acceptable austenitic tungsten, nickel, chromium and molybdenum based alloy that is having well-improvised resistance ability against stress corrosion cracking, pitting and crevice corrosion. The high content of chromium is providing excellent oxidizing media resistance and tungsten & molybdenum is giving excellent resistance to the oxidizing aqueous media including mixtures containing oxidizing/nitric acid and wet chlorine. Also, it resists acetic acid, seawater, etc.
