Incoloy 926 Characteristic：
1.It has high resistance to pitting and crevice corrosion when inHalide and H2S contained acid media.
2.In practice, effective in resistance of chloride stress corrosioncracking.
3.A variety of corrosion have good corrosion resistance capabilityin the normal oxidation and restore environment.
4.Upgrade mechanical properties than Cronifer 1925 LC-Alloy 904L.
5. Alloys has Improved the stability of metallurgical compared to arange of 18% of the nickel content alloys.
6.With a certification of applied in manufacturing-related pressure vessel （VdTUV-196～400℃ and ASME ）
Metallurgical structure
926 is face-centered cubic lattice structure.
Corrosion resistance
926 is an austenitic stainless steel alloy has a similar chemicalcomposition with 904L alloy, its nitrogen content is 0.2%,molybdenum content is 6.5%. Molybdenum and nitrogen contentsignificantly increased the resistance of pitting and crevicecorrosion in the halide media.Meantime, nickel and nitrogennot only ensures the stability of metallographical, but also reduceseparating intergranular trend in the thermal process or weldingprocess better than the nitrogen content of nickel alloy. 926 hasparticular corrosion resistance in the chloride ions medium due tothe excellent local corrosion resistance and 25% nickel alloycontent.A variety of experiments in the 10000-70000ppm of Chlorideconcentration, PH 5-6, 50-68℃ operating temperature of the slurryof limestone FGD system show that, after a 1-2 year trial period,926 alloy without pitting and crevice corrosion.926 in otherchemical media also has good corrosion resistance in the hightemperature and high concentration of media, including sulfuricacid, phosphoric acid, acid gas, sea water, salt and organicacids.926 is the material that choosed for BAM directory Chapter 6of "dangerous goods storage and transportation containersnorms" by Berlin, Germany's national Institute forMaterials Research and Testing (BAM) . In addition, in order tohave the best corrosion resistance only when the material is in theright state of metallurgy and guarantee clean conditions.
