Abstract:
A method for producing a brake disk for passenger cars, characterized in that the brake disk is formed by stamping, precision cutting or cold forming from a hot-and-cold-rolled steel strip of a steel consisting of:0.2 to 0.3% of carbon up to 1.0% of silicon up to 1.5% of manganese up to 0.01% of sulfur 12 to 15% of chromium up to 1.0% of nickel 0.6 to 1.2% of molybdenum, the remainder being iron and production-related impurities, wherein the carbon and chromium content is selected so that precipitation of primary carbides and delta ferrite is prevented and the steel is subjected to a heat treatment by annealing, hardening and tempering.
