Yes.

A further stipulation: Yes, if material is not subject to imnpact testing.

I was under the impression that austenitic stainless steel alloys are typically exempt from impact testing.

Indeed, but certain applications like cryogenic service in B31.3 may require impact testing, even for austenitic stainless steels I think.

I should have added the deposited weld metal under materials - not just the base metal.
