摘要:
A cold rolled steel sheet for a gasket material, characterized in that it has a chemical composition, in wt %: C: 0.08 to 0.60%, Si: 1.0 to 3.0%, Mn: 0.5 to 3.0%, P≦0.06%, S;≦0.06%, Al: ≦0.1%, N: 0.0010 to 0.0150%, and the balance: Fe and inevitable impurities: and a method for producing the steel sheet. The cold collect steel sheet for a gasket material can provide a good balance between bead formability and spring characteristics, together with excellent gas sealing property, and can be produced at a low cost, and thus can be used for producing a gasket being suitably used at openings such as those for cooling water and a lubricating oil and a bolt hole.
