Shock Absorber Tube Carbon Steel Cold Drawn Bright Precision Welded Tube For Automotive
Cold Drawn Shock Absorber Tube with High Dimensional Accuracy for Automotive Applications
Material
This carbon steel cold-drawn, bright, precision-welded tube is specifically designed for automotive applications, particularly for use as shock absorber cylinders and related structural/hydraulic components. The manufacturing process involves forming a welded pre-tube shell followed by precise cold drawing to achieve tight tolerances, excellent surface finish, and superior dimensional control.
Specification
  • Process: Welded shell with cold draw finish
  • Outer Diameter (OD): Customizable from 10 mm to 400 mm
  • Wall Thickness (WT): 1 mm to 35 mm or more
  • Length: Up to 12,000 mm or per customer requirements
  • Surface: Bright cold-drawn finish with polished straightness
  • Tolerance: Tight dimensional control per precision tube standards
Key Features
  • High dimensional accuracy
  • Smooth bright surface finish
  • Improved mechanical properties
  • Good weldability and cost-effectiveness
  • Automotive-specific performance
Our Advantages
  • Strict control of straightness and concentricity
  • Tight tolerances on outer diameter and wall thickness
  • Optimized mechanical properties through cold-drawing
  • Material traceability and comprehensive inspection
  • Flexibility in engineering and customization
  • Specialization in automotive supply chain requirements
