What is difference between SA 516 60 & SA 515 60

[dajoshi]

Can anyone tell me the difference between SA 516 60 & SA 515 60.
I assume that SA 516 60 has fine grain structure and the other has course.
So SA 516 60 can be used for lower temperature application where as SA 515 60 is used for higher temp. applications.
Please let me know is i am correct.
Also let me know if there are some additional points.

Yes, you are correct.

Hi Joshi!
Agreed with you regarding grain structure. But, for the temperature purpose, it should be other way, like Sa 515-60 can be used for intermediate to higher temperature purpose(specifically boilers) and SA516-60 is used for lower to intermediate temperature purpose(specifically for vessels).
The title for each material has been defined in ASME 2007 BPV code it self. Regards, Tejash
