1.4539 super stainless steel pipes and tubes

904L(UNS N08904) (1.4539) pipes and tubes

• Alloy material production export 
• Grade:
  • 1.4539 super stainless steel pipes and tubes
  • 904L(UNS N08904) (1.4539) pipes and tubes
• Properties of 1.4539 super stainless steel pipes:
  • 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 inter-granular corrosion
•  Applications 904L(UNS N08904) (1.4539) pipes and tubes :
  • Equipment like reactors for petro-chemical industry.
  • Gas desulfurization equipment, like tower shell, flue, and shutter spray system
  • Washers and fans used in organic acid process system.
  • Equipment for sea water processing, paper making, sulfur, nitric acid and pharmacy
