Alloy 20 Pipe ASTM B729 N08020 DIN 17751 2.4660 is a high-corrosion resistant alloy, which shows very good resistance to phosphoric acid, nitric acid, sulfuric acid in chloric media. DIN 17751 2.4660 Alloy 20 is chiefly used in the chemical industry, apparatus engineering and heat exchanger.

 

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. This alloy is often chosen to solve SCC problems, which may occur with 316L stainless.
