Definitions

  • the present invention relates to a steel and the processing method for the production of high-strength fracture-severable machine components. 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 lubrication the components (thermo-mechanical treatment) and a matched heat treatment after forging or hot working.
  • 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 % V (C70S6, 70MnVS4) or medium carbon content of about 0.4% C, about 1% Mn, 0.06-0.07% S and about 0.3% V (36MnVS4) according to technical customer specifications.
  • These steels have a largely pearlitic structure with vanadium carbides and manganese sulfides and comply with the specifications regarding the mechanical properties.
  • Disadvantages of the known material variants are that the previous material variants have a high resource consumption of expensive and scarce alloying agents.
  • vanadium is increasingly being used in the field of precipitation-hardening ferritic-pearlitic steels (AFP steels), making vanadium an increasingly scarce commodity.
  • the aim 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.
  • the high value for the yield strength is achieved in addition to the basic chemical composition by a precipitation of finely divided carbides of the special carbide formers niobium and vanadium.
  • 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 differentiated 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. Decisive for a good crackability of the material is a crystalline fracture without macroscopic deformation. This is dictated by the alloy concept of high carbon, nitrogen and sulfur content and comparatively low levels of chromium, nickel and molybdenum.
  • the invention relates to a steel for producing fracture-separable components for the vehicle industry with the following chemical composition in percent by weight:

Abstract

L'invention concerne un acier et un procédé de transformation pour produire des pièces mécaniques pouvant être séparées par rupture présentant une résistance accrue, ces pièces étant constituées d'au moins deux parties pouvant être séparées par rupture. L'invention se caractérise en ce que la composition chimique de l'acier est la suivante (en pourcentage en poids) : 0,40% = C = 0,60%; 0,20% = Si = 1,00%; 0,50% = Mn = 1,50%; 0% = Cr = 1,00%; 0% = Ni = 0,50%; 0% = Mo = 0,20%; 0% = Nb = 0,050%; 0% = V = 0,30%; 0% = AI = 0,05%; 0,005% = N = 0,020%, le reste étant constitué de fer et des impuretés et résidus issus de la production de l'acier.
