ALLOY 20
Description
Solid wire for matching Alloy 20
Solid wire rod matching Alloy 20 that results in a fully austenitic weld metal rich in Cu with high resistance to corrosion in sulphuric acid, mineral acids and organic acids. Alloy 20 is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless. Typical applications include tanks and vessels, piping, cast pumps, valves, heat exchanger and other components used in chemical processing, metal cleaning and pickling industries.
