Manufacture of torsion bars

摘要

A method of making high performance torsion bars from austenitic stainless steels which comprises the steps of fabricating a blank complete with splined ends and torsion working said blank below the Md temperature of the material to a stress value above 80-90% of its ultimate. Prior working may be done in tension at below the Md temperature, and subsequent precipitation hardening may be added to the basic process.
