Creep failure of type 310 austenitic stainless steel bolts

A number of type 310 austenitic stainless steel (UNS S31000) bolts used to hold radiant heating pipe guides to a superheater wall surface frequently failed after a short period (several months) of service. In the most recent inspection (during a turnaround in July 1999), several bolts exhibited seve...

Summary:A number of type 310 austenitic stainless steel (UNS S31000) bolts used to hold radiant heating pipe guides to a superheater wall surface frequently failed after a short period (several months) of service. In the most recent inspection (during a turnaround in July 1999), several bolts exhibited severe distortion while others had fractured into two separate pieces. The on-site investigation showed a flat fracture surface typical of brittle fracture. In order to ascertain the main cause of failure, several failed bolts were subjected to detailed metallurgical investigations.
