Austenitic Stainless Steel 316
Austenitic Stainless Steel 316
(OP)
I have specs of Gate Valve with Body & Bonnet A351 CF3M (316L). The specs also mentions to submit report of microstructure / average grain size as per ASTM E112 for austenitic stainless steel as per applicable ASTM Specification. Though 316L is austenitic stainless steel, but it is not clear for me if this test is required for 316L as per E112. I read the standard but could not find this point. Can anyone help me.

A report of grain structure isn't needed to fulfil the requirements of ASTM A351.

Normally you do a Practice A but if the results are inconclusive you move to a practice B or C.

Dear reverman (Mechanical)& SJones - Many thanks for your advise. Based on advise from Ripz, I saw A351 & learned that it does not call for microstructure / average grain size tests. Please send your advise.
