Bearing steel has enormous hardness. With bending strength, bearing steel can withstand high stress and centrifugal forces. Bearing steel materials can eighter be through-hardened or case-hardened. To ensure purity, vacuum-processing is necessary. Bearing steel is magnetic in nature and is a good thermal and electrical conductor.
