HASTELLOY TUBE Grade C22 manufacturer

A most adaptable item like nickel-chromium-molybdenum-tungsten compound accessible today with enhanced imperviousness to both confined and uniform erosion and additionally to a mixed bag of blended modern chemicals yet the Hastelloy C-22 alloy shows unrivaled weld ability and is utilized as weld overlay consumables over and combination filler wire to enhance imperviousness to consumption.

Hastelloy C-22 composite has extraordinary imperviousness to a wide mixture of substance procedure situations, including solid oxidizers, for example, cupric and ferric chlorides, chlorine, hot defiled arrangements like (inorganic and natural), acidic anhydride and acidic acids, formic, and seawater and saline solution arrangements. Hastelloy C-22 alloy opposes the arrangement of grain-limit hastens in the weld warmth influenced zone, therefore making it suitable for most substance procedure applications in the as-welded condition.

Alloy 22 is nickel-base and normally contains 22% chromium, 14% molybdenum, and 3% tungsten. Iron is ordinarily restricted to under 3%. The combination's high substance of chromium issues it great imperviousness to wet erosion by oxidizing media (e.g., nitric corrosive and ferric and cupric salts). Its substance of molybdenum and tungsten give the alloy imperviousness to wet decreasing media (e.g., sulfuric and hydrochloric acids). Alloy 22 displays fantastic imperviousness to destructive assault via seawater under stagnant and streaming conditions.

At hoisted temperatures, the high chromium level of Hastelloy C-22 Alloy helps it oppose oxidation, carburization, and sulfidation. Since it is nickel-base, combination 22 opposes high temperature assault by halides (e.g., chlorides and fluorides). With these properties, the compound is broadly used to ensure steel tubes and different segments in coal-let go and waste-to-vitality boilers.

Official Steel supplies Hastelloy C22 as plate, sheet, strip, bar, wire, pipe, tubing, pipe fittings and flanges.

Hastelloy C-22 ought not to be utilized as a part of administration temperatures over 1250° F because of the development of inconvenient stages which structure over this temperature.

Hastelloy C22® gives imperviousness to general consumption, setting, fissure erosion, intergranular assault, and anxiety erosion splitting. Hastelloy C22® can be utilized for some applications, for example, marine, power, substance transforming, contamination control, paper handling, and waste transfer commercial ventures. Hastelloy C22® contains chromium, molybdenum, tungsten, and iron which makes the composite impervious to erosion in stagnant or streaming seawater. The composite is structured by gas tungsten-bend, gas metal - curve, and protected metal-circular segment.
