Duplex Steel Grade:

Duplex Stainlss Steel SAF 2205(UNS S32205, S31803), Super duplex SAF 2507 (UNS S32750), S32760, S32304 etc.

SAF 2205 is the most common grade for duplex stainless steel, ASME/ASTM grade is UNS S32205 or the similar grade S31803 , equivalent to EN/DIN 1.4462.

SAF 2507 is a super duplex steel, the ASTM grade is S32750, equivalent to EN/DIN 1.4410. We can supply super duplex pipes and fittings in high quality and fast delivery time.


What We Do for Duplex 2205 Pipe:

Our sister company is mainly focus on the manufacturing of duplex stainless steel pipe, with good experience and reliable quality control system. Nowadays, Kaysuns supplies both duplex stainless steel pipe and super duplex stainless steel pipes and tubes.

Super duplex 2507 pipe is a super duplex steel pipe with 25% chromium, 4% molybdenum, and 7% nickel. The common grade of super duplex steel is Saf 5027 / S32750, S32760, they have similar composition and mechanical properties. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion. Compared to duplex stainless steel pipe, super duplex steel pipe SAF 2507 is highly resistant to uniform corrosion by organic acids such as formic and acetic acid.


Manufacturing of Duplex 2205 Stainless Steel Pipe

Cold drawn and cold rolled is the mainly process for seamless duplex stainless steel pipe. Due to the material characteristic of high strength and hardness, duplex steel is more difficult to process than austenitic steel. It is very easy to damage, especially for small thickness and large diameter pipes , it has a long and hard-working procedures, that's why the delivery time of duplex steel pipe is long.


Our Strength:

  • Supply both seamless and welded.
  • 10 years experience for fabrication and supplying.
  • Computer temperature controlled heat treatment facility.
  • Reliable based material vendor management.
  • Testing laboratory of NDT and PMI etc.
  • Mill certificate to EN10204 3.1/3.2.
