Due to several mistakes, I have some components made from 304/304L (welded with ER308L) went through PWHT at 1325F for 2 hours, cooled slowly to 800F and then air cooled. I understand that at this temperature, austinitic stainless steel can become sensitized. From what I've read, the amount of sensitization is somewhat dependent on the amount of carbon in the material, with higher carbon content resulting in higher sensitization. With this dual grade material, the maximum carbon content should be 0.030%, limited by the 304L.
How much of a concern would you have with sensitization of these parts?
