GCr15 hot rolled bearing steel round bar
GCr15 is a high-quality high-carbon chromium alloy bearing steel widely used for manufacturing bearing components such as balls and rings. It features uniform chemical composition, high purity, well-distributed carbides, excellent wear resistance, high contact fatigue strength, and good machinability after spheroidizing annealing. It is equivalent to AISI 52100 and DIN 100Cr6.
