Summary
This article addresses the critical safety implications of using heat during the straightening process, noting that heat can permanently damage the molecular structure and strength of certain steels. It highlights that OEMs have specific steel repairability matrices and temperature limits that must be followed to ensure passenger safety.
What to do on the job
Always identify the specific type of steel being repaired and consult the OEM-specific guidelines and temperature limits before applying any heat during the straightening process.
How to use it
Use this document to justify the time and research required to identify specific steel types and OEM-specific heating limits. It serves as a foundational reference to defend why heat cannot be arbitrarily applied to modern vehicle structures during pulling and straightening operations without risking passenger safety.
