AP Surface Super Duplex Steel Seamless Pipe Sch40 ASTM A790 S32750 2 1/2”

In technical terms, Super Duplex pipes are made from a form of austenitic-ferritic stainless steel, based upon iron with alloying additions of chromium, nickel and molybdenum. As such, Super Duplex pipes are pipes made out of

this material. Super duplex pipes combine the features of ferritic steel and of austenitic steel. This means this material possesses high strength from the ferritic structure and high corrosion resistance from the austenitic structure, plus the ability to resist stress corrosion cracking. They have good toughness, are readily available and more competitively priced than other corrosion resistant metals that use higher contents of expensive alloying additions.
