Product details

Alloy 20 is an austenitic nickel-iron-chromium-molybdenum alloy with copper additions. This combination makes it more suitable for applications involving sulfuric, phosphoric and nitric acids. The chromium and molybdenum content provides good resistance to pitting and crevice corrosion. This grade offers excellent resistance to chloride-induced stress corrosion cracking (SCC). Alloy 20 can be used in a variety of chemical process environments and has good performance in most acids, alkalis, salts and seawater.
