Corrosion resistance:

AL-6XN (UNS N08367) is a super austenitic stainless steel with excellent resistance to chloride ion pitting and crevice corrosion As a corrosion-resistant alloy with good cost performance ratio, its comprehensive corrosion resistance has a great leap over 316L. At the same time, compared with other corrosion-resistant nickel base alloys such as C-276, its corrosion resistance is close, and its cost advantage is obvious. Due to the addition of significant nitrogen in the alloy, AL-6XN material has higher tensile strength than conventional austenitic stainless steel (such as 304316317), while maintaining excellent material toughness and impact strength The allowable stress value specified in ASME standard, AL-6XN is 40% higher than 316L and nearly twice higher than copper nickel alloy. Typical working condition: 60% sulfuric acid, below 80 ℃, annual corrosion rate <0.1mm

Application fields:

Chemical vessels and pipelines, installation systems of offshore oil and gas platforms, condensers in contact with seawater or crude oil, heat exchangers and piping systems, filter presses in pulp bleaching, storage tanks and pressure rollers, flue gas desulfurization equipment (FGD) in thermal power plants, steel mills, petrochemical enterprises, crude oil distillation towers and fillers, desalination equipment and pumps, servo water piping systems in nuclear power plants, transformer tanks exposed to the marine environment Pharmaceutical equipment (for the purity of drugs), food production equipment
