is a nickel-iron-chromium alloy bar with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. The alloy is especially resistant to sulphuric and phosphoric acids. INCOLOY alloy 825 is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
Round bar steel: 1mm to 2000mm Square-shape steel: 50mm to 600mm Plate steel:0.5mm to 1000mm Width: 10-1500mm
