Products line up and applications

Seamless standard tubes

  • Multiple variety
  • Meet various standards, ASTM, ASME,TüV etc
  • Wide range of diameter, wall thickness, and length

347AP (UNS S34751) (Anti-Polythionic Acid)

  • 347AP is a modified type347 stainless steel which has been developed for desulfuring plants in the petroleum refinery industries. 347AP has high resistance to polythionic acid SCC on welded joints without post-weld heat treatment. The steel has a high temperature strength equivalent to that of TP347 and better weldability than TP347. 347AP stainless steel offers property advantages over conventional TP321 and TP347 stainless steels.

Ni and Ni-base alloy

  • Ni and Ni-base alloy used as a material for severe corrosion conditions and for high temperature application

Super Duplex (DP3W)

  • High corrosion resistance, especially in Cl solution and in acidic environments
