Allegheny technologies incorporated [ati] is one of the world`s largest and most diversified producers of specialty metals. Ati produces a wide variety of stainless steel alloys known for their excellent corrosion and heat resistance. Superaustenitic stainless steels is made of the same structure as the common austenitic alloys, but they have enhanced levels of elements such as chromium, nickel, molybdenum, copper, and nitrogen, which give them superior strength and corrosion resistance. Different types of superaustenitic stainless steels are:
Al 20 - flue gas scrubbers, sulphur acid tanks and racks, process piping, heat exchangers, manufacture of solvents / explosives/plastics/synthetic fibers/organic chemicals/pharmaceuticals
Al 4565 - desalination, seawater piping, offshore oil production, pollution control [fgd]
Al 904l - high efficiency furnace vent pipe, pulp & paper processing equipment, welding electrodes and fittings.
Al-6xn plus - desalination, seawater piping and critical components on offshore oil platforms
Js700® - wet scrubbers in municipal incinerators, wet-process phosphoric acid plants, chlorine dioxide pulp bleaching.
