Propeller shaft

Jansen Steel Tubes produces weld-drawn tubes to produce propeller shafts for the automotive industry. As part of processing tubes are partly drawn in at the ends to meet high demands to reshaping properties and the quality of the weld seam. Stringent tolerances in terms of roundness, straightness and wall thickness are necessary to prevent running noise and vibrations. This guarantees smooth propeller shaft operation within the vehicle. The use of cutting-edge air hardening steel materials enable additional options to cut weight.

Tube requirements

  • Excellent formability (drawing in, hammering)
  • High torsional strength and durability
  • Very good welding properties
  • High geometrical accuracy (eccentricity, roundness)
  • Excellent surface condition

Material properties

  • High torsional strength and fatigue strength
  • Excellent reforming properties
  • Homogeneous strength properties and ductility
  • Excellently suitable for welding

Structure

  • Homogeneous, fine-grain structure in weld seam and basic material
  • Minimised surface decarburisation of inner and outer surfaces (< 100 μm)
  • Very good weld seam quality
  • Very good reforming properties

Geometry

  • Minimised fluctuations in wall thickness and inner/outer diameter
  • Minimised deviations in straightness
  • Minimised deviations in concentricity and axial run-out
  • Minimised eccentricity
  • Specific tube end processing: sawn/brushed; chamfered

Surface

  • Excellent surface condition
  • Minimised surface flaws (adhesions, scratches, dents, etc.)
  • Minimised corrosion protection, optionally specific corrosion protection
