Bearing Steel SAE 52100 / GCr15 / SUJ2 / 100Cr6 / EN31
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..
