I haven't seen such a serious and earnest technical discussion in a long time, thank you. As a material supplier, we are struggling with whether or not to do heat treating for orders of A928 S32750 super duplex welded pipe.
It is a fact that most super duplex welded pipes and butt-weld fittings to A815, the manufacturer does not do heat treatment. This is not just because of cost, but because of the nature of duplex steel. It will be deformed too easily when heated. Especially for thin wall thickness pipes and fittings, once heat treated they can be completely deformed or even scrapped, which is a huge challenge for the manufacturer. And in practice, there is a few complaints caused by the lack of heat treatment.
