Abstract (en)

[origin: EP1566460A1] 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. <IMAGE>
