Thank you for the response GDD.
ASME Sec VIII DIV2 part 5 allows usage of DBA procedures as long as allowable stress is governed by time independent properties. Time independent limit of 3Cr-1Mo materials for Div 2 Cl 2 is below 475 degC. This allows design of 3Cr-1Mo up to 474 degC using DBA...
Hi Members,
As per ASME Sec VIII Div 2 Cl2, 3Cr-1Mo creep limit is below 475 degC. But fatigue curves are not available in Sec VIII div 2 or API 579 or in STP-PT-096 – 2022 for 3Cr-1Mo . Could someone advise how we can do a fatigue analysis with a cyclic operation between 430 degC to 470 degC...
