Definitions

  • the present invention relates to a steel and the processing method for the manufacture of higher-strength machine components, which consist of at least two fracture-separated parts. This material was developed, for example, for the production of cracking pipes.
  • the steel must be suitable for forging or other hot forming.
  • Forged heat with controlled cooling requires the setting of a largely pearlitic structure with a yield strength of more than 750 N / mm 2 , a tensile strength of 1000 to 1200 N / mm 2 , an elongation at break of more than 10% and a fracture rate of more than 25% , Particularly important is the suitability for fracture separation.
  • the desired properties can be achieved by the targeted adjustment of a pearlitic structure with precipitates of special carbides (niobium and vanadium carbides) and of manganese sulfides by a correspondingly adjusted chemical composition, a targeted temperature control during hot forming during the production of the starting material and in the final forging of the components (thermomechanical treatment) and a matched heat treatment after forging or hot forging.
  • steels of almost eutectoid composition having about 0.7% C, 0.5 to 0.9% Mn, 0.06 to 0.07% S and optionally 0.1 to 0.2 are used % V (C70S6, 70MnVS4) or with average carbon content of about 0.4% C, about 1% Mn, 0.06 to 0.07% S and about 0.3% V (36MnVS4) according to technical customer specifications.
  • the object of the present invention is to avoid the mentioned disadvantages by proposing a new steel which has the required mechanical properties in terms of strength (and fatigue strength) and in addition combines good toughness properties in the tensile test with simultaneously good crackability.
  • the steel should be readily pourable and forgeable.
  • the new steel should be able to be produced in a way that saves resources compared to the known steels by a partial substitution of the vanadium content by niobium with a correspondingly adapted forming and cooling strategy.
  • a crackable steel is also from the EP 0779 375 B1 known. However, the addition of niobium is not provided here.
  • the high value for the yield strength is achieved in accordance with the invention in addition to the basic chemical composition by precipitation of carbides of the carbide blanks, niobium and vanadium, which are dispersed as finely as possible.
  • a resolution of the existing carbides before the last hot forming step is required as well as a controlled temperature control during hot forming and the subsequent cooling.
  • Finely divided precipitates can be achieved in particular with a low final forming temperature followed by slightly accelerated cooling. As a result, in particular the yield strength is increased and thus the yield ratio significantly improved.
  • the tensile strength can be improved from the base value given by the base composition with 0.5% C, 0.6% Si, 1.0% Mn, 0.23% Cr, 0.2% Ni and 0.14% V by a slightly accelerated Cooling after hot forming can also be set in the desired range.
  • the toughness characteristics are limited in particular by the targeted addition of 0.06 to 0.07% sulfur. Also positive in this sense are the carbon content and the relatively high nitrogen content.
  • the invention relates to a steel for producing fracture-separable components for the vehicle industry according to claim 1.
