Duplex Stainless Steel Pipe

Duplex Stainless Steel Pipe

Duplex stainless steel pipe is austenite-ferrite dual phase stainless steel pipe, it is developed for applications that demand high strength and corrosion resistance.  Duplex stainless steel pipe is a cost effective solution for many applications where the 300 series stainless steel pipe are susceptible to chloride stress corrosion cracking. Duplex stainless steel pipe is an idea choice for the applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

Available Grade

Duplex SAF2205(UNS S32205, S31803), Super duplex SAF2507 (UNS S32750), S32760, S32304 etc.

Product Description:

We can offer both duplex stainless steel pipe and super duplex stainless steel pipes and tubes. Super duplex stainless steel pipe is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. 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 of SAF2507 is highly resistant to uniform corrosion by organic acids such as formic and acetic acid.
