HASTELLOY@C22
Is all-around nickel-chromium-molybdenum-tungsten alloy. It has better bulk corrosion resistivity than the others, likes HASTELLOY C276, alloy C4 and alloy 625. Alloy C22 has well resistance in pitting, crevice corrosion and the ability of stress-corrosion cracking, and also has perfect resistance in oxidized acid and reductic acid, like wet chlorine, nitric acid, oxidized acid with chloride ion, ferric chloride, copper chloride, chlorine, methanoic acid, ethanoic acid, acetic anhydride, sea water and saline. HASTELLOY C22 could resist crystal boundary precipitaion in welding heat-affected zone, and this characteristic let alloy may adapt multiple application in many process about chemical engineering.
