What is Alloy 20 Flanges :

Alloy 20 (Carpenter 20) Flanges 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 forged flanges has practical immunity to chloride stress corrosion cracking. This alloy 20 flanges are often chosen to solve SCC problems, which may occur with 316L stainless flanges normally.
