Difference between SA 516 Gr. 60 and 70 (w.r.t. vessel service)
Difference between SA 516 Gr. 60 and 70 (w.r.t. vessel service)
(OP)
Hi All,
Just wondering if there is a difference between SA 516 Gr. 60 and 70 from equipment service point of view.
Other than material strength, is there any other deciding factor when chosing these two materials?
Thanks

There are SCC situations in refinery service where you prefer Gr 60 (or Gr 55) with a maximum tensile strength below the allowable max. in ASTM A516.
Shmulik - not automatically. Better ductility does not necessarily bring better low temperature fracture toughness.
