STE in addition to providing consulting services is expanding its business scope to import and deliver different types of Steel Sections.

Carbon Alloy:

  • A333, Gr. 6, A335 P5, P11, P22, P91
  • Copper Alloy:
  • Admiralty Brass tube (C44300)
  • Al‐Brass Tube (C68700)
  • Cu‐ Ni Tube (C70600, C71000, C71500, C71640)

Duplex:

  • UNS S32750 is a high‐alloy super duplex stainless steel for service under extremely corrosive conditions. It is developed mainly for chloride containing environments like seawater and, therefore, it contains high amounts of chromium, molybdenum and nitrogen.
  • UNS S31803 is a medium – alloy duplex stainless steel with high corrosion resistance. This steel is the most widely used of the three. Continual development work for many years has led to increased nitrogen and molybdenum contents, thus father improving the weld ability and corrosion resistance.
  • UNS S32304 is a low‐alloy duplex stainless steel. It contains no molybdenum and has lower nickel content then the other two. It is the developed as a high strength and low‐cost alternative to the standard austenitic grades 304L and 316L.
  • Ni‐Mo Alloy
  • Hastelloy Gr. B
  • HASTELLOY GR. C
  • Ni‐Cr Alloy
  • Inconel 600
  • Inconel 625
  • Ni‐cu Alloy
  • Inconel 800
  • Inconel 825

Due to the best relationship with the fitting manufacturers, we can supply all types of fittings with the Most appropriate delivery condition (including price and time) according to the below items:
