Straightening And Heat: Ford/Lincoln
I-CAR · May 29, 2020 · Ford, Lincoln
Summary
Ford and Lincoln provide a Recommended Steel Repairability Matrix in section 501-25 of their Workshop manuals that outlines specific rules for straightening steel with or without heat. This matrix details approved temperature ranges, maximum heating times, and the maximum number of heat applications allowed based on the steel type.
What to do on the job
Consult the Ford/Lincoln Recommended Steel Repairability Matrix in section 501-25 of the Workshop manual to verify temperature limits, heating times, and application limits before applying heat to any steel component.
How to use it
Use this document to justify the time and equipment needed to monitor temperatures (such as using digital thermometers or temp crayons) when straightening HSLA or other approved steels, and to defend the necessary replacement of structural components when the matrix prohibits heating or straightening.
