摘要：<p>Seal assembly (201) for a subsea well assembly with inner and outer circular sealing surfaces (215a, 215b) in an annulus (211). It has a seal ring (203) with a cross section exhibiting two legs (205a, 205b), with seal ring seal surfaces (209a, 209b). The seal ring comprises a main metal section (217) having metal with the same or higher degree of hardness than the metal in said facing circular sealing surfaces (215a, 215b). The seal ring seal surfaces comprise a seal ring surface metal (210a, 210b) which is of a softer metal than the metal in the circular sealing surfaces (215a, 215b) and the metal in the main metal section (217). The seal ring (203) comprises a second section (219) comprising said seal ring surface metal (210a, 210b), the second section (219) extending continuously between said seal ring seal surfaces (209a, 209b) on the respective legs.</p>
