1.Steel crown with letter "G" denotes rolling bearing steel.
2.The carbon content of high carbon chromium bearing steel can not be marked, and the chromium content is expressed in thousandths, such as GCr15. The steel number representation of carburized bearing steel is basically the same as that of alloy structural steel.
