Definitions

  • the hardness of this steel was 51-52 HR.
  • the notch impact strength measured on five test pieces was between 29 and 31 mkp/cm.
  • test pieces of the same steel were heat treated by the conventional method of quenching followed by tempering and were found to possess a hardness of 51-52 l-lRc as well.
  • the notch impact strength of these samples was only at the 2.5-3.5 mkp/cm
  • the instant invention is therefor the use of particular steels having 06-09%C, 0.5-1.0% Si, 0.41.0% Mn, 0.4-1.0% Cr, 0.2-0.8 Mo, O.3l.0% Ni, possibly up to 0,3 Ti and/or V, remainder iron and residual impurities, in bainitic hardened condition with a hardness of 46-54 l-lRc for the manufacture of chain saws.
  • This steel is also very suitable for long-band-saws, which are particularly stressed by buckling at the sides.
  • a sawblade consisting essentially of 0.6-0.9% C, 0.5-1.0% Si, 0.4-1.0% Mn, O.4l.0% Cr, 0.20.8% Mo, 0.3-1 .0% Ni, at least one element in an amount of up to 0.3% selected from the group consisting of Ti or V, remainder iron and residual impurities; the microstructure of the sawblade being bainitic which has been hardened to a hardness range of 46-54 HR.
