Incoloy alloy 926 is a nickel-iron-chromium alloy with additions of molybdenum, nitrogen.


Corrosion Resistance

Good resistance to pitting and crevice corrosion in the halide media. Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating inter-granular trend in the thermal process or welding process better than the nitrogen content of alloy 926 has particular corrosion resistance in the chloride ions medium due to the excellent local corrosion resistance and 25% nickel alloy content. A variety of experiments in the 10000-70000ppm of Chloride concentration, PH 5-6, 50-68℃ operating temperature of the slurry of limestone FGD system show that, after a 1-2 year trial period, 926 alloy without pitting and crevice corrosion. Alloy 926 in other

chemical media also has good corrosion resistance in the high temperature and high concentration of media, including sulfuric acid, phosphoric acid, acid gas, sea water, salt and organic acids.
