Product Description
GB GCr15 bearing steel is GB standard Alloy Bearing steel, It
belong to the high quality high carbon, alloy chromium,manganese
steel.
GB GCr15 properties is a chromium,manganese alloy steel
specification. GCr15 is equivalent to AISI 52100, DIN 100Cr6. Most
applications can replace each others.
