When cold formed extensively the grain size yields a visibly undulated surface called “orange peel”. 800HT can be welded by the common techniques used in stainless steels.Incoloy 800ht Flanges and the 800H flanges which have lower carbon contents. The low carbon content allows for better welding and to increase the toughness of the flanges.
