Alloy 20 is designed to withstand sulfuric acid. Its nickel, chromium, molybdenum and copper content all provide excellent general corrosion resistance. Restricted carbon and columbium stabilization allows the use of welded fabrication in corrosive environments, usually without post-weld heat treatment. Alloy 20 with 33% nickel is practically immune to chloride stress corrosion cracking. This alloy is often chosen to solve the SCC problems that can arise with 316L stainless steel.
