Patent ID: 10989303

Abstract:
A cylinder head gasket includes a composite member formed of a metal substrate and a rubber layer provided to both surfaces of the substrate. The substrate is formed of stainless steel having a content of C that is 0 to 0.15 mass %, a content of Si that is 0 to 0.5 mass %, a content of Mn that is 0 to 2.0 mass %, a content of Cr that is 11.5 to 13.0 mass %, a content of N that is 0 to 0.5 mass %, a content of P that is 0 to 0.040 mass %, a content of S that is 0 to 0.030 mass %, a content of Ni that is 0 to 0.6 mass %, the balance Fe, and inevitable impurities. The stainless steel forming the substrate has a 0.2% proof stress of 1,300 to 1,500 MPa.
