Alloy 20 CB-3® is an austenitic stainless steel possessing excellent resistance to attack by sulfuric acid and many other aggressive environments. Alloy 20 CB-3 stainless is also stabilizes to limit inter-granular attack, even in the sensitized condition. Important advantages of alloy 20 CB-3 stainless are its excellent mechanical properties and comparative ease of fabrication. The presence of Columbium in the alloy minimizes the precipitation of carbides during welding.
