  • Patent number: 5451276
    Abstract: A process is disclosed for producing a ski edge made of quenched and subsequently tempered steel having a head (2) that comprises the running surface and a flank (4) that projects into the body of the ski. The profiled edge (1) is at first rolled, then quenched and subsequently tempered over its whole cross-section. Afterwards, the flank (4) is partially tempered and provided in a separate operation with punched out openings. In order to obtain with this process a totally straight ski edge, the deviation in Rockwell hardness, seen in the direction of the cross-section and length of the profiled edge is set at less than 2.degree. HRC during quenching and subsequent tempering of the whole profiled edge. The warming-up temperature and duration during partial warming-up of the edge are the same over the whole length of the profile edge and the profiled edge is subjected to a constant bending strain before being punched.
