Definitions

  • the high strength of steel produced according to the invention is achieved by the combined use of precipitation, fine grain and mixed crystal strengthening.
  • the selected contents of the alloying elements C and Mn lead to the desired solid solution strengthening.
  • the primary material By bringing the primary material to a temperature of 1300 ° C to 1350 ° C before the preliminary rolling, the precipitates of the alloy elements Ti, V and Nb which may be present are completely dissolved.
  • the degrees of deformation set during the subsequent pre-deformation lead to a fine, evenly distributed and recrystallized austenite grain.
