  • PRODUCTS DESCRIPTION

  • UNS N08367 ASTM B 688, B 691, B 675 / 676 B 462, B 366, B 564, B 804 Forms of AL-6XN Available at Mega Mex Sheet
    Plate
    Bar
    Pipe & Tube (welded & seamless)
    Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lapjoints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
    Corrosion Resistance
    Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media. Chromium is the principal agent for conferring corrosion resistance in neutral or oxidizing environments. Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure. Nickel and molybdenum both provide increased resistance to chloride stress corrosion cracking in reducing environments.
    What are the characteristics of AL-6XN?
    Excellent resistance to pitting and crevice corrosion in chloride solutions
    Practical immunity to stress corrosion in NaCl environments
    High Strength and toughness
