Abstract: A metal C-shaped ring gasket is constructed so that a satisfactory sealing property can be obtained even with a low clamping pressure. The metal C-shaped ring gasket is made of an austenite stainless steel and constructed so as to have a superficial roughness below 0.2 &mgr;m Ra and a superficial hardness below 230 Hv by electrolytic polishing.
