Corrosion resistance
926 is an austenitic stainless steel alloy has a similar chemical composition with 904L alloy, its nitrogen content is 0.2%, molybdenum content is 6.5%. Molybdenum and nitrogen content significantly increased the resistance of pitting and crevice corrosion in the halide media.Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating intergranular trend in the thermal process or welding process better than the nitrogen content of nickel alloy. 926 has particular corrosion resistance in the chloride ions medium due to the excellent local corrosion resistance and 25% nickel alloy content.
Alloy 926 is a multipurpose material can be applied in many industrial:
- Fire system, water purification system, marine engineering and hydraulic piping perfusion system
- The pipeline, joint, air systems in the acidic gas production
- Evaporator, the heat exchanger, filter, mixer, etc. in the phosphate production
- Power plants condensation and pipe system in the use of sewage water to cool water
- The use of acidic organic catalyst chlorinated derivatives production
- The production of cellulose pulp bleacher
- Polished bar in the orrosive oil wells
- Hose system in the ocean engineering
- Flue gas desulphurization system components
- Sulfuric acid condensation and separation system
- Crystalline salt concentration and the evaporator
- Transport of corrosive chemicals containers
- Reverse osmosis desalination plant
