was wondering does API 6a sec 5.8 and annex M heat treating equipment qualification does this section only pertain to manufactured parts getting heat treatment after machining or is it when raw material is purchased with heat treat tempature requirments. because if its needed through raw material purchase im having problem gettting calibration records due to steel suppliers purchase out of country. i had one audtor tell me doesnt matter and an API auditor say no because it impossible to recieve from raw material suppliers but yes if you do it after machining stage. can anyone shed any light on this thanks.
