885°F Embrittlement of Super Duplex Stainless Steel Impeller in Hot Off Gas Blower

Sudharsanan Soundararajan
...Abstract During Start-up of Hot off Gas blower, catastrophic brittle fracture was observed on the final stage impeller of 4 stage Hot off gas blower. The metallurgy of the impeller is Super Duplex stainless Steel (UNS S32750) and the 4th stage of the blower was continuously operated above 325°C...

Comparison of the Life Cycle Cost of Carbon Steel, Duplex Stainless Steels, Super Austenitic, and Nickel-Based Alloys for Crude Unit Overheard Condensers

Karen Picker, Luiza Esteves
... overhead condensers that suffered severe corrosion leading to premature failure after just 6 months in service. The metallurgy of the tube bundles was later upgraded to super duplex, UNS S32750, and hyper duplex stainless steel (DSS), S32707, which extended the service life to 12 months and two years...
