Hastelloy C-22 Metallurgical structure
Hastelloy C22 is face-centered cubic lattice structure.
Hastelloy C-22 Corrosion resistance
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 resistancebetter.Hastelloy C22 is one of a few material that can resist thecorrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloyhave prominent corrosion resistanceto high concentration chlorate( iron chloride and copper chloride).
