Thanks first of all. We are a pressure vessels manufacturer and we have welded for many years reactors and others made of Cr-Mo materials, mainly P4. The way we apply the DHT treatment often depends on the client`s requirements but we do not have any clear criteria to propose in the case that no...
Does anybody have a good information (probably a link) about the convenience or real effects in the use of Dehydrogenation Heat Treatment (DHT) after welding for welds in P4 and P5 materials?
