UNS N08020 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. This alloy is often chosen to solve SCC problems, which may occur with 316L stainless.
Alloy 20 is widely used in Sulfuric acid pickling tanks, hooks and heating coils,Phosphate coating drums and racks, Heat exchangers, Distillation columns and intervals, Mixing tanks, Chemical and petroleum process equipment
