Polythionic Acid Stress Corrosion Cracking: Temperature ranges

  • 1.  Polythionic Acid Stress Corrosion Cracking: Temperature ranges

    Posted 02-14-2022 09:17 AM
    API  571 states that at operating temp above  370  series 300 stainless steels are at risk from PTA, SCC. But stabilized 321/347 and other  austenitic alloys can be operated safely above this. 

    Does anyone have any views on what alloys  such as 321. 6% moly and other alloys can be operated at? 

    Thanks
