SS type 410 is a P-No 6 material? so the min temp. for PWHT as per Section VIII-1 is 760 degC. However, PWHT is not required for that grade when the conditions of note (a) - Table UHA-32-1 are met.
You are invited to read carrefully the 1st paragraph of UCL-34, especialy if you have welded with an austenitic filler metal
