Novel Tough Micro-Alloyed Bearing Steel with High Hardenability

Source

A near-eutectoid lower-carbon vanadium-alloyed steel has been under consideration for bearing steel components where improved toughness, and therefore better micro-defect tolerance, is required. Due to the steel’s relatively lower concentration of carbon—that is, compared with a typical approximately 1 wt.% C through-hardened bearing steel, the hardenability was found to be higher. The steel design and heat treatment concepts have been investigated experimentally using, for example, dilatometry and transmission electron microscopy characterizing small-scale lab melts. The novel steel has been designed with a particular focus on continuous casting as a suitable process.
