A nickel-iron-chromium alloy with additions of copper and molybdenum. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. The alloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric and nitric acids. Used for tanks, piping, heat exchangers, pumps, valves and other process equipment. Standard product forms are round, flats, pipe, tube, plate, sheet, strip and wire.
