ASTM B668 UNS N08028/Alloy 28/1.4563/Sanicro 28 Super Alloy Seamless Pipe China Origin

Alloy 28 (UNS N08028, W. Nr. 1.4563) is a nickel-iron-chromium alloy with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localise attack such as pitting and crevice corrosion. The alloy are especially resistant to sulphuric and phosphoric acid. Used for chemical processing, pollution control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment.

Advantages of UNS N08028

• Very high corrosion resistance in strong acids
• Very good resistance to stress corrosion cracking (SCC) and intergranular corrosion in various environments
• High resistance to pitting and crevice corrosion
• Good weldability
