FAQ
What is a super duplex pipe?
Super duplex pipes combine high strength from the ferritic structure and excellent corrosion resistance from the austenitic structure, along with superior resistance to stress corrosion cracking.
What is super duplex tubing?
Super duplex tubing, like S32750, features a mixed microstructure of austenite and ferrite, offering enhanced strength and corrosion resistance compared to traditional ferritic and austenitic steels.
