Alloy 825 tube is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium, and provide exceptional resistance to many corrosive environments. The alloy's high nickel content makes it enough to resist chloride-ion stress-corrosion cracking. The combination of nickel, molybdenum and copper gives it outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also aids resistance to pitting and crevice corrosion. In addition, The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion.
