Alloy 28 is a nickel-iron-chromium alloy with additions of molybdenum and copper. It has a high resistance to pitting, cursive corrosion and to stress-corrosion. Developed as a material for service is highly aggressive and corrosive environments. The alloy are especially resistant to sulfuric and phosphoric acid. The alloy 28 has a similar specification as alloy 825 tube.
