How to harden a steel bolt

Web31 jan. 2024 · The idea here was to trim the remnants off and then drill a hole in what was left so that it could be safety-wired shut. I knew going in that by cutting (with a cut-off wheel) and grinding the linkage it would work harden. That didn’t seem to be too big of a problem because I could anneal it after trimming it to shape. WebWork hardening of materials is a condition that should be avoided while machining. It is caused when heat generated by the cutting tool transfers to the workpiece material and causes plastic deformation. The process is similar to a heat treatment of the workpiece but on a lower scale.
