  Verfahren zur Herstellung von     Holzbearbeitungesägen.       Zur Herstellung vergüteter     Holzbearbei-          tungssägen,    wie Gatter-, Kreis- und Band  sägen, sind     unlegierte    oder niedrig legierte       Stähle        mit        0,50        bis        1,00%        Kohlenstoff        üblich.     Für naturharte Sägen zur Holzbearbeitung       wurden        Stähle        mit        0,

  30        bis        0,60%        Kohlen-          stoff,        0,10        bis        0,50%        Mangan,        0,-10        bis        2,00%          Silizium,        0,50        bis        3,00%        Wolfram        und        0,50          bis        1,

  50%        Chrom        vorgeschlagen,        in        welchen     das     Wolfram    ganz oder teilweise durch     Molyb-          dän    ersetzt und zur Erhöhung der Leistungs  fähigkeit     Vanadium    zugesetzt sein kann. Ein  weiterer Vorschlag ging dahin,     Sägeketten    so  wie Band-, Gatter- und Kreissägen zur Holz  bearbeitung aus bis zur Grenze der     Feilbar-          keit    vergüteten Federstählen herzustellen.  



  Die Erfindung bezweckt, die Leistungs  fähigkeit von Sägen zur Holzbearbeitung zu  erhöhen und betrifft ein Verfahren zur Her  stellung von     Holzbearbeitungssägen,    welches  dadurch gekennzeichnet ist, dass diese Sägen       aus        einem        Stahl        mit        0,80        bis        1,80        %        Kohlen-          stoff        und        1,00        bis        12,

  00%        Chrom        hergestellt     werden. Vorzugsweise enthält der Stahl zur  Verbesserung seiner Eigenschaften, insbeson  dere seiner     Schnittleistung-,    noch 0,10 bis       3,00%        Vanadium.        Er        kann        zu        dem        gleichen          Zweck        ausserdem        noch        0,20        bis        0,

  90%        Wolf-          ram    enthalten, das ganz oder teilweise durch       Molybdän    ersetzt sein kann.  



  Es hat sich wider Erwarten gezeigt, dass  diese Stähle allen     Anforderungen    entsprechen,    die an sie bei ihrer Verarbeitung zu Holz  bearbeitungssägen gestellt werden, darüber  hinaus aber noch eine bedeutend höhere  Schnittleistung als bekannte     Holzsägenstähle     aufweisen.  



  So hatten zum Beispiel vergütete     Gatter-          sägen        ans        einem        Stahl        mit        etwa        1,10%        C,          0,35        %        Mn,        0,20        %        Si,        1,20        %        Cr        und        0,

  35        %        V     gegenüber bekannten vergüteten     Gattersägen     unter gleichen Versuchsbedingungen eine  zweieinhalbfache Schnittdauer ergeben.



  Process for the manufacture of woodworking saws. Unalloyed or low-alloy steels with 0.50 to 1.00% carbon are common for the production of tempered woodworking saws, such as frame saws, circular saws and band saws. For naturally hard saws for woodworking, steels with 0,

  30 to 0.60% carbon, 0.10 to 0.50% manganese, 0, -10 to 2.00% silicon, 0.50 to 3.00% tungsten and 0.50 to 1,

  Proposed 50% chromium, in which the tungsten completely or partially replaced by molybdenum and vanadium can be added to increase the performance. Another suggestion was to manufacture saw chains such as band, frame and circular saws for working wood from spring steels tempered to the limit of filability.



  The invention aims to increase the performance of saws for woodworking and relates to a method for the manufacture of woodworking saws, which is characterized in that these saws are made of a steel with 0.80 to 1.80% carbon and 1.00 until 12,

  00% chromium are made. The steel preferably contains 0.10 to 3.00% vanadium to improve its properties, in particular its cutting performance. For the same purpose he can also add 0.20 to 0,

  Contains 90% tungsten, which can be completely or partially replaced by molybdenum.



  Contrary to expectations, it has been shown that these steels meet all the requirements that are placed on them when they are processed into woodworking saws, but also have a significantly higher cutting performance than known wood saw steels.



  For example, tempered frame saws had a steel with about 1.10% C, 0.35% Mn, 0.20% Si, 1.20% Cr and 0,

  35% V compared to known tempered frame saws under the same test conditions result in two and a half times the cutting time.
