Alloy 20 was designed specifically to withstand sulfuric acid. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment. At 33% nickel, Alloy 20 has practical immunity to chloride stress corrosion cracking.
Alloy 20 is an austenitic iron-base alloy, with excellent corrosion resistance. When comparing costs between this alloy and other higher cost alloys, the selection of Alloy 20 could result in a cost savings based on whether this alloy can meet the necessary resistance. Such applications are limited to a max temp of 1000°F per the ASME specification.
Using traditional methods Alloy 20 can either be cold or hot worked. Resistant to pitting and crevice corrosion, this alloy is an excellent option. Welding this alloy can be done through MIG, TIG and SAW (submerged arc welding).
