Alloy 20 is alloy formulated of nickel, molybdenum, chromium and copper which equips it with distinguished resistance to acid attacks, general corrosion, crevice corrosion and pitting. The chemistry in the alloy defies the oxidizing environment that involves chlorides and sulfuric acid, nitric acid, and phosphoric acid. The alloy consists of niobium for equilibrium against sensitization delivering intergranular corrosion. The alloy has impressive mechanical properties at both nominal and extreme temperatures. There are many different stainless steel grades in this category which have their unique characteristics and properties in different conditions and environments.
