SA182 Vs SA965
SA182 Vs SA965
(OP)
Hi
I recently met a case, where for a Heat Exchanger, tubesheet is specified to be of SA965 Gr 316L. However, my suppliers intends (and infact has already procured) material with SA182 Gr 316L material. On comparing, I find that the material chemical composition and mechanical properties are all the same. The term "High Temperature" is used in the title of both specifications. Could someone throw some light over what is the basis difference in these two specifications and do I have a premise to reject SA182 Gr 316L material used by supplier instead of SA965 Gr 216 material? (the premise I am looking for here should be purely technical, no contractual).
Thanks in advance for your advice.
Regards
Shashank

Thanks Metengr, however, an SA182 material can very well be "forged" upto a weight of 4540kgs as per standard. Hope you would not differ from this. In such a case, how do you conclude that if made to SA182, then the tubesheet would be rolled and not forged?
As for the case particular, the supplier is using forging made to SA182.
If you are right then the forging cannot be certified to SA182. If not, then principally there is no difference in materials of similar grades of SA965 AND SA182? Your reply would be appreciated.
