Hastelloy C22 Alloy SB 622 N06022 Alloy
ASTM B622 ASME SB 622 N06022 Hastelloy C22 2.4602 Alloy Characteristic:
ASTM B622 ASME SB 622 N06022 Hastelloy C22 2.4602 Nickel Alloy possess prominent resistance performance to different chemical environments, including strong oxidizing matter, such as iron chloride, copper chloride, chlorine, heat pollution liquid(organic and inorganic), formic acid, acetic acid, acetyl oxide, seawater and salting liquid and so on. Hastelloy C22 alloy can resist the grain boundary precipitate form when jointing heat affected zone, this performance made it can applied in many kinds of chemical processing.

Hastelloy C22 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten makethis corrosion resistance better.Hastelloy C22 is one of a few material that can resist the corrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).
Austenitic stainless steel are made using up to 80% scrap iron. Not only is stainless steel an alloy of iron, but depending on the fabrication process, it can be loaded with tramp elements and inclusions detrimental to finishing requirements and corrosion resistance. Austenitic stainless steel have been the workhorse of the sanitary food and pharmaceutical industry for years. However, for reasons mentioned above, processors are beginning to use more corrosion resistant alloys to achieve the required life-cycles for their systems. One such material is Hastelloy® C-22®.
ASTM B622 ASME SB 622 N06022 C22 alloy is one of the most versatile nickel-chromium-molybdenum-tungsten alloys available today. This alloy demonstrates improved corrosion resistance to both uniform and localized corrosion and will exceed the performance of C276, C4 and alloy 625 in a variety of corrosive environments.
