Abstract

Disclosed is a particular type of fine-austenitic-grain globular-sulfides resulfurized carbon and/or alloy steel suitable for casehardening and hardening-tempering treatments, with the addition of transition metals of Group III (rare earth metals or lanthanides), in form of non-coated wire or wire coated with metals, metal alloys or still other coatings, such as ceramic coating or other types of coatings. The addition of rare earths as metal wire to ingot mould or tundish allows rare earth elements to be perfectly diffused and homogenized throughout the product and globular sulfides to be homogeneously distributed as well throughout the cast section; the resulting steel displays better machinability properties than steel produced by means of traditional techniques.
