INCOLOY 825

没有此类产品
产品描述
A nickel-iron-chromium alloy with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, stress-corrosion cracking and localized attack such as pitting and crevice corrosion. The alloy is especially resistant to sulfuric and phosphoric acids. Used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment.
STANDARD PRODUCT FORMS
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging
stock, hexagon and wire.
