ASTM A790 UNS S32750 / SAF2507 Super Duplex Stainless Steel Seamless Pipe For Sea Water Treated

 

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 is 2507 duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid.
