A steel material composition, in particular for producing piston rings and cylinder liners, comprises the following elements in the listed quantities relative to 100% by weight of the steel material: 0.5-1.2% by weight C, 0-3.0% by weight Cr, 72.0-94.5% by weight Fe, 3.0-15.0% by weight Mn and 2.0-10.0% by weight Si. The compostion can be produced by producing a melt of the starting materials and casting the melt into a pre-fabricated mold. |
