It has to be before PWHT otherwise heat treatment itself can cause sigma phase embrittlement or 885 F embrittlement of austenitic stainless steels; chances of which increase with higher ferrite content. Therefore, in order to perform a heat treatment without having any possible embrittlement, a prior measurement of ferrite content is necessary.

Dear Ezat This casting is a defective casting could be an old and used, as now a days the valves suppliers pick up the scrapped castings also and use them after a bit of cleaning/painting. This is clearly seen in this case as the neck shows the signs of having some sort of putty filled and dressed up. The other possibility is that it is a 3rd Grade casting used to meet the urgent requirements. The recommendation is that IT SHOULD NOT BE ACCEPTED.

Hi Kishore, you can get those recommended datas from manufacturers Catalogues , like ESAB, Hyundai, Lincoln, Thyssen,  whatever brand you have selected. for each size and the position of welding . Before making PQR, you should always refer to the welding manufacturer's recommendation for Amps, Volts, polarity, type of coating, AWS Classes etc .

Dear Ali, Your specification calls the requirement for B7M to avoid the corrosion under insulation.  B7M bolting is often opted for in corrosive environments due to its heat treatment & hardness. B7  bolting also can be used if it is used for non exposed to  corrosive environment which means we can substitute the B7 bolting with B7M for  corrosive  environment.
