Katariya steel is one of the foremost manufacturers, distributors, and exporters of Hastelloy C22 / C2000 / B2 / B3 Flanges. Grade B2 / B3 flanges are nickel-molybdenum alloys that have properties such as excellent stability against inter-granular corrosion. Incoloy B3 and B4 have the same amount of Nickel content, i.e. around 65 percent, and also, the same amount of carbon content, i.e. around 0.01 percent in their overall chemical composition. Super-alloy C22 / C2000 can be used in applications requiring more than 540°C (1000°F) temperature. Nickel-chromium-molybdenum based alloy grade C22 / C2000 flanges have good metallurgic stability.
Alloy grade B3 / B4 flanges have extraordinary immunity against reductive media such as hydrochloric acid and sulfuric acid. Hastelloy C2000 Lap Joint Flanges and C22 socket Weld Ring Flanges have excellent immunity to oxidation and creep corrosion. Nickel alloy B2 Flanges resist the formation of grain boundary carbide precipitates in the weld heat-affected area. Threaded Ring Flange grade C22 is in demand due to its versatility and the extraordinary resilience to chloride-induced pitting. Some of the Major uses of Super Alloy C22 & C2000 are Chlorination systems, Flue gas scrubbers, chemical process equipment, Acid production, and pickling systems. Hastelloy B3 flanges can also withstand sulfuric, acetic, formic, and phosphoric acids along with other non-oxidizing media.
