When it comes to Super Duplex Steel Boiler Tubing, it’s typically made using grades like UNS S32750 and S32760. These grades boast a dual-phase austenitic-ferritic structure, which provides impressive tensile strength (around 750 MPa) and yield strength (over 550 MPa). Additionally, the tubing offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. With a density of about 7.8 g/cm³, Super Duplex boiler tubes maintain mechanical stability at high temperatures, exhibit excellent weldability, and promise a long operational life even under high pressure and thermal stress, making them ideal for critical boiler systems and heat exchangers.
