AL-6XN is typical of 6 molybdenum (high molybdenum content 6.3%) super austenitic stainless steel. Resistance to chloride pitting corrosion, crevice corrosion and stress corrosion resistance is superior to 3 series stainless steel, the cost is lower than the corrosion resistant nickel base alloy. In a variety of serious corrosion environment showing a good corrosion resistance, suitable for high chloride aqueous solution and chloride corrosion environment. Used in a variety of high chloride environments: bleach (sodium hypochlorite, chlorine dioxide), halogen and chemicals with high salt or sea water content. Offshore platform, nuclear industry, pharmaceutical industry, food industry and papermaking equipment; flue gas desulfurization pipeline lining; petrochemical distillation tower; high pressure heater; thin wall condensation pipe cooling seawater; steam surface condenser and multifunctional heating furnace. AL-6XN high chromium, molybdenum, nickel and nitrogen so that AL-6XN has better resistance to chloride pitting corrosion and crevice corrosion, which makes the application of AL-6XN in many environment: flue gas desulfurization spray tower; equipment and pump reverse osmosis desalination; chemical reactor and pipeline; heat exchanger using seawater; crude oil distillation tower and filler metal; marine oil and gas exploration equipment; pulp bleaching scrubber system in the drum, roller, groove, pipeline etc.. Super AL-6XN stainless steel is a kind of high Mo austenitic stainless steel containing N, has thirty years of history in the industrial application, the world wide application of thousands of marine engineering, seawater desalination, flue gas desulfurization, petroleum chemical industry, food industry, paper industry and other industrial fields. AL-6XN stainless steel is designed for seawater corrosion resistant super stainless steel, high Cr, Mo, Ni ratio of alloying elements containing N has good resistance to corrosion, corrosion in acidic environment with chloride ions in breeder crevice corrosion, intergranular corrosion, stress corrosion. The hardware platform has good mechanical properties. The welding performance, easy manufacture and equipment installed in the field. AL-6XN has a 300 series stainless steel is more excellent resistance to corrosion, crevice corrosion, crystal valve corrosion, stress corrosion and uniform corrosion. AL-6XN alloy has high resistance to crevice corrosion. Because AL-6XN has excellent corrosion resistance, crevice corrosion and erosion resistance in seawater, it is widely used in ocean engineering to replace copper alloy with AL-6XN in America and Europe. The offshore drilling platform, which is used in the sea water pipeline system, all kinds of heat exchange equipment, the supporting structure of the seawater splash zone.
