<p>The invention relates to a method for manufacturing a cutting blade, which cutting blade (T) is meant particularly to be used as a rotating cutter blade, such as a slitter blade in a paper machine, and, which is manufactured from a blade preform (1), being provided with a cutting surface (2). The blade preform (1) comprises a frame part (I1 ), being made of a basic material and in which on an attachment surface (3), existing essentially at a cutting area of the cutting blade to be manufactured, is processed at least a wear resistant material layer (4) that forms the cutting surface, the layer consisting of steel (Cmin.= 2,5 %) that is alloyed with tungsten or chromium (Wmin. or Crmin.= 4 %) and vanadium (Vmin. = 10 %). The invention relates also to a cutting blade, being manufactured according to the method, and use of an auxiliary material in manufacturing thereof.</p> |
