Alloy C22 (Hastelloy C22) Plate, Hastelloy C-22 Alloy Plate

Product Code : AL-C22-NN-SP

ALLOY22 is a Ni-Cr-Mo alloy containing W and extremely low carbon and Si contents. “The chemical composition of Alloy 22 has been designed ,The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, seawater, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi-purpose plants where such “upset” conditions occur frequently. Alloy 22 is also resistant to many reducing media. As a result it can be used for equipment in polyvalent chemical plant where widely varying conditions may be encountered. The very low carbon content of Alloy 22, together with its balanced composition, reduce the tendency to formation of grain-boundary precipitates in the heat-affected zone during welding,thus making it suitable in the as-welded condition for many applications in the chemical process industry.” Alloy C-22 should not be used in service temperatures above 1250° F due to the formation of detrimental phases that form above this temperature.
