ASME SA790 S32750 2507 S25073 Duplex Steel Pipe DIN1.4410 Seamless Tube
Duplex Steel Grade:
Duplex Stainlss Steel 2205(UNS S32205, S31803), Super duplex 2507 (UNS S32750), S32760, S32304 etc.
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.
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 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 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.
