How does stress relieving differ on a high strength steel rail compared with a rail made out of mild steel?

What will be an ideal response?


The old theory of using a heavy sledge hammer and beating on the surface of the frame rail no longer applies, especially on the undercarriage of a unibody vehicle which is typically made of one or more varieties of high strength steel. When hammering to stress relieve around the repair area with high strength steels a much larger surface must be addressed and must be done with more finesse such as using a spoon to distribute the blow over a larger area avoiding the creating of hammer dimples. It is also best to use a lighter weight hammer to avoid making numerous indentations on the surface.
