Definitions

  • the invention relates to the use of a steel alloy as a material for the production of dynamically loaded pipe components and such a pipe component.
  • stabilizers which are used to reduce the tendency of the body to curve and to influence the self-steering behavior. They stiffen the suspension in one-sided load, since the resistance of the material of the stabilizer of the side slope resiliently counteracts.
  • Another example would be a torsionally loaded shaft.
  • Stabilizers are to be assigned with regard to the type of stress straight torsion springs or torsion bars, since a stabilizer at different Compression of the wheels is twisted about its longitudinal axis.
  • From the EP 0 753 595 B1 it is known to produce stabilizers from pipes. In this case, one makes the more favorable in a tube ratio of the moment of resistance against torsion to the tube mass in comparison to a solid rod advantage.
  • the materials used would have to maintain a higher by approximately a factor of 1.4 yield strength and tensile strength as materials of solid rods while maintaining the design in the vehicles structurally predetermined or usable outer diameter.
  • Another important factor for achieving a high permanent fatigue strength is the surface quality of the outer and inner surface of the tubes used.
  • the best surface qualities have longitudinally welded and possibly subsequently cold drawn tubes made of rolled steel strip. In this case, the errors occurring in seamless drawn pipes, such as pleats, etc., avoided.
  • this tensile strength is insufficient to compete with stabilizers of a higher strength solid material.
  • Even the steel 34MnB5 steel used to date for tubes for the manufacture of stabilizers only achieves tensile strengths of up to 1,800 MPa, but with a relatively low fatigue strength.
  • the state of the art also includes the EP 1 698 712 , which discloses a steel material for highly loaded springs, having the following composition: C 0.35 - 0.65%, Si 1.4 - 2.5%, Mn 0.1 - 1.0%, Cr> 2.0% , Ni> 1.0%, Cu> 1.0%, P> 0.020%, S> 0.020%, N> 0.006%, Al> 0.1% and balance iron. Although this steel also achieves strengths up to about 2,100 MPa.
  • High Ti and Al levels involve the risk of reduced fatigue strength, which can be attributed to the formation of hard phases. Titanium contents in the range greater than 0.01% lead to the primary precipitation of hard titanium nitrides, which produce internal notches in the material and have a negative influence on the fatigue strength of high-strength spring steels. Aluminum contents greater than 0.01% also lead to the formation of aluminum oxides and aluminum nitrides having the above-described negative fatigue properties. Furthermore, this steel material is at a copper content above 0.2% for the tube manufacturing process, d. H. Stretch reduction, less suitable and also expensive in view of the relatively high nickel content. A copper content of more than 0.2% leads to grain boundary failure during hot forming, especially if, as in the case of pipe production, there are existing high stresses in hot working.
  • the surface quality plays an important role.
  • the improvement of the surface quality can be achieved with seamless pipes by internal peeling, ie by a machining, which is associated with high costs and thus has a low cost.
  • the invention is based on the object to show the use of a steel alloy as a material for the production of dynamically loaded pipe components, wherein the material meets the high requirements for the production of dynamically loaded tubular components, in particular for the production of straight or tortuous torsion springs, such.
  • Coil springs, or hollow shafts is suitable and also reached the strength level of spring steels.
  • the steel material can still be welded even if the carbon content is greater than 0.35%, so that the production method for dynamically loaded pipe components a) both welding and drawing, b) direct welding, and c) seamless production are suitable ,
  • the good weldability is achieved by a comparatively high ductility in the weld area, so that a reduced tendency for brittle failure of the weld during cooling and when calibrating the tubes is present.
  • This can be attributed to the finest lamellae made of retained austenite in the hardened structure. In the transmission electron microscope, these lamellae become visible in the nanometer range. These lamellas increase the ductility of the hardness structure without lowering the yield strength and strength.
  • the lamellae have an average particle size of 60-70 nm.
  • a seamless production is particularly suitable in combination with an optimized internal machining, if the wall thickness s in a range greater than 18% of the outer diameter D is (s / D> 18%).
  • the material according to the invention is therefore suitable for all tube production methods mentioned above, is also inexpensive to produce and has the potential due to high achievable strength values, for torsionally loaded components, e.g. Torsion spring to replace solid materials.
  • the quenching is carried out by preferably inductive heating to Austenitmaschinestemperatur of 900 - 950 ° C, followed by quenching in water or oil (preferably water at a cooling rate> 200 K / s, in particular> 400 K / s) and then tempering to a Temperature of 200-300 ° C, preferably ⁇ 275 ° C, in particular to a temperature of 250 ° C.
  • dynamic loadable pipe components in diameter ranges from 3mm to 150 mm, especially in diameter ranges from 8 mm to 50 mm can be produced.
  • the wall thickness is preferably 10% to 22% of the outer diameter of the pipe component in such dynamically loaded pipe components.
  • the production of the pipe components is preferably carried out in soft annealed, pearlitic state.
  • the steel alloy no. 1 is the material as it is to be used in the pipe components according to the invention.
  • the comparison material no. 2 corresponds to the alloy 34MnB5.
  • the comparison material no. 3 corresponds to the alloy 25MnB5.
  • the comparison material no. 4 corresponds to the alloy 42CrMo4.
