产品描述
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
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging
stock, hexagon and wire.
