Abstract A solid lubricant such as MoS2 is applied to medium to high carbon and stainless steels after surface voids have been produced in the material, as by a final annealing operation, but before a final cold working operation reduces the material to finished size. The latter operation embeds or includes the lubricant into the material and thereby provides a superior lubricated steel for piston ring, shaft, valve stem, spring, stranded wire and the like applications. The technique involved may also employ corrosion inhibiting agents to increase resis- tance to corrosion of the steel as well as to improve its lubricity.
