Incoloy 926 is an austenitic stainless steel alloy, similar to 904 L alloy, with 0.2% nitrogen and 6.5% molybdenum content.Molybdenum and nitrogen content greatly increase crevice corrosion resistance.At the same time, nickel and nitrogen can not only improve the stability, but also reduce the tendency to separate the crystallization thermal process or welding process is better than the nitrogen content of nickel alloy.926 has certain corrosion resistance in chloride ions due to local corrosion properties and 25% nickel alloy content.A variety of experiments at concentrations of 10,000-70,000 PPM, pH 5-6,50 ~68℃ operating temperature, limestone desulfurization island slurry show that 926 alloy is free from crevice corrosion and pitting during the 1-2 year trial period.926 alloy also has excellent corrosion resistance in other chemical media at high temperature, high concentration media, including sulfuric acid, phosphoric acid, acid gas, sea water, salt and organic acids.In addition, in order to obtain the best corrosion resistance, ensure regular cleaning.
