transition temperatures for a312 stainless
transition temperatures for a312 stainless
(OP)
Where can I find transition temps for a312 in the code books.
I'm just starting as a level 1 welding inspector,QC (Canada) and just learning.
Thanks

Because this filler has a significant amount of ferrite, the impact transition temperature will vary and is not reported in Code books. However, ASME Section VIII, Div 1 does provide some guidance relative to low temperature service and cryogenic service and impact testing requirements.
This filler metal would be limited to the impact test requirements in UHA-51 of ASME Section VIII, Div 1.

are you sure you are not talking about A312-TP304 & A312-TP316 or some other tubular product?

Type 304 stainless steel does not have a ductile to brittle transition temperature so you will not see one published code books or otherwise. Type 304 and other austenitic grades of stainless steel can be safely used down to -320 deg F and even lower because the predominant stable phase in these metals is austenite.
