Incoloy 25-6mo Forging

A super-austenitic containing 6% molybedenum and offering excellent corrosion-resistance to neutral and acidic environments containing chlorides or other halides, such as what is found in air pollution control and flue gas desulfurization systems. The molybdenum and nitrogen content provide resistance to pitting and crevice corrosion, while copper enhances resistance to sulfuric acid. The alloy is especially suited for service in high-chloride environments such as brackish water, seawater, caustic chlorides and pulp mill bleach systems.STANDARD PRODUCT FORMSPipe, tube, sheet, strip, plate, round bar, forging stockand wire.MAJOR SPECIFICATIONSUNS N08925, N08926ASTM A 240, A 480, B 366,B 472, B 625, B 649, B 673,B 674, B 677, B 751, B 775,B 804, B 829W.
