We have a pressure vessel which will be post weld heat treated. The vessel materials is SA516-70. Trays materials is 410S stainless steel. The trays are seal welded to the support ring (Carbon Steel).
We plan to perform the whole vessel PWHT after the seal weld of tray to support ring. But we worry about the distortion and warping of trays during PWHT due to the thin thickness of tray and different thermal coefficient of carbon steel and 410S.
Does anybody has the experience before? please advise. Thanks.
