904L super stainless steel pipes and tubes

• Alloy material production export
• 904L super stainless steel pipes and tubes
• UNS N08904 super stainless steel pipes and tubes
• 1.4539 super stainless steel pipes and tubes
• Properties of 904L super stainless steel pipes and tubes:
  • Super stainless steel, low carbon, high Ni and Mo.
  • Good activation-passivation transition ability, good resistance to sulfur, acetic acid, methane acid and phosphoric acid corrosion.
  • With low carbon (max 0.020%),there is no carbide precipitation in normal heat treatment and welding, thus eliminating subsequent risk of intergranular corrosion
• Applications of 904L super stainless steel pipes and tubes:
  • Equipment like reactors for petro-chemical industry
  • Gas desulfurization equipment, like tower shell, flue, shutter spray system
  • Washers and fans used in organic acid process system.
  • Equipment for sea water processing, paper making, sulfur, nitric acid and pharmacy
  • Food equipment/jars/bottles; centrifugal machine, reactors used in pharmaceutical factory
