Stabilizer
Jansen Steel Tubes 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)
