SB163 SB423 N08825 Nickel Alloy Seamless Tubes Tubing Pipes is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids， to stress-corrosion cracking， and to localized attack such as pitting and crevice corrosion. Alloy 825 Incoloy 825 is especially resistant to sulfuric acids and phosphoric acids. This nickel steel alloy is used for chemical processing， pollution-control equipment， oil and gas well piping， nuclear fuel reprocessing， acid production， and pickling equipment.
