Alloy 20,N08020,2.4660,ASTM B463
A nickel-iron-chromium alloy with additions of copperand molybdenum. It also contains niobium for stabilization againstsensitization and resultant intergranular corrosion. The alloy has excellentresistance to general corrosion, pitting, and crevice corrosion in chemicalscontaining chlorides and sulfuric, phosphoric, and nitric acids. Used fortanks, piping, heat exchangers, pumps, valves, and other process equipment.
