Are you planning to use high-strength tubing but are concerned about bending and performance issues? Bake hardening could be an option to consider during the design phase.

This webinar included:


  • applications for HSS tubes
  • limitations for bending HSS tubes 
  • bake hardening as a way to increase strength and other properties after tube-bending 
  • tests performed and results

The use of tubing made from high-strength steel has become increasingly common within the automobile industry in recent years. However,  from a design perspective working with high-strength tubes can present challenges due to limitations regarding the minimum bending-radii. When referring to the mechanical properties of tubes in general, tensile testing is often conducted on untreated tubes, without considering the increase in strength achieved through bake hardening.  

This presentation showed some examples of this process and potential benefits, depending on tube diameter and wall thickness, of applying the bake hardening technique
