Kas,
The material I am using is definitely not along the same lines as drill rod.
Linear rod is a precision ground, hardened bar used in such applications as
material handling/packaging equipment, where linear motion ball bearing
units are required.
I am getting the specification sheet for this material, but haven't seen it
as yet. Typical mechanical properties for this material will be similar to
the below: -
Hardened & ground - inch dimensions. Steel: Ck60 Surface hardness: 62
Tensile strength: 550-750 N/mm
Kind Regards
Peter Vucinic
