ASTM A790 UNS32750 Duplex Stainless Steel Seamless / Welded Pipes

S32750 is a super duplex stainless steel that has a higher chromium, molybdenum, and nickel content compared to S31803. This makes it more resistant to corrosion and pitting in aggressive environments such as seawater and chemical processing plants. S31803 is a standard duplex stainless steel that is also highly resistant to corrosion and has good mechanical properties. It is commonly used in industries such as oil and gas, chemical processing, and pulp and paper.
