What material is N08020?
Alloy 20 (UNS N08020) is an austenitic, nickel-iron-chromium based superalloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion. It is also stabilized with Columbium to minimize carbide precipitation during welding.
YUHONG Group has been operating stainless steel/duplex/nickel alloy seamless pipe for more than 30 years, and has been exporting more than 80,000 tons of stainless steel/duplex/nickel seamless steel pipe every year. Our clients have covered more than 75 countries.
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.
