Definitions

  • the known from the prior art wear steels are designed to be extremely hard for their purpose and accordingly have a high strength in conjunction with a limited ductility.
  • the high hardness required for a wear steel aims at a sufficiently high resistance to abrasive wear.
  • the object of the present invention is to provide a Q & P steel with which complex geometry components for wear applications can be made.
  • the Q & P steel or the component produced from the Q & P steel in addition to Fe and unavoidable impurities in terms of production by weight consists of:
  • the Q & P steel is preferably a hot strip with a tensile strength (R m ) between 800 and 1500 MPa, a yield strength (R e ) of above 700 MPa, an elongation at break (A 50 ) between 7 and 25% according to DIN EN ISO 6892 and one very good formability, z. B. a hole widening> 20% according to DIN ISO 16630.
  • the Si content is further restricted, for example for reasons of the desired surface quality, AI with a minimum content of 0.5% by weight is added to the cementite suppression.
  • S Sulfur
  • MnS or (Mn, Fe) S Sulfur
  • MnS or (Mn, Fe) S Sulfur
  • the S content is limited to a maximum of 0.003 wt .-%.
  • the Q & P steel described here can also be alloyed with micro-alloying elements (MLE), such as V, Ti or Nb. These elements can contribute to higher strength by forming very finely divided carbides (or carbonitrides with the simultaneous presence of N). The mode of action of these three elements, however, varies in severity.
  • MLE content leads to a freezing of the grain and phase boundaries after the hot rolling process during the partitioning step, which favors the desired property combination of grain refining and formability.
  • the minimum MLE content for Ti is 0.02 wt%, for Nb 0.01 wt%, and for V, 0.1 wt%.
  • KAM Kernel Average Misalignment
  • Figure 1 is a perspective view of an excavator spoon. Description of the Preferred Embodiments
  • Mn 1.5-3.0%, preferably Mn: 1.9-2.7%,
