Stabilizer

Jansen produces welded and welded-drawn precision steel tubes meeting the highest quality standards made of high-tensile grade steels for stabilizers. The application in the area of the automotive industry is very reliant on quality. Any failure of the component must not be relevant to safety. A possibility of lightweight construction is the production of the tubes in drawn version with varying wall thicknesses or by using high-tensile materials, which allow additional weight reduction.

Tube requirements

  • Very good formability
  • High torsional strength and durability
  • Very good welding propertiess
  • High geometrical accuracy
  • Excellent surface condition

Material properties

  • High strength, in particular heat treatment (Q+T) rather than just tempering (T)
  • Excellent reforming properties
  • Minimised residual stress
  • Potential to reduce wall thickness

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 eccentricity
  • Specific tube end processing: sawn/brushed; chamfered

Surface

  • Minimised surface flaws (adhesions, scratches, dents, etc.)
  • Minimised corrosion protection, optionally specific corrosion protection
  • Increase of compressive stresses through shot peening (outside/ inside diameter)
