Description:
GB/T 18254 GCr4 is a kind of high-carbon chromium bearing steel.GCr4 bearing steel is a low hardenability steel with good impact resistance . And also GB/T 18254 GCr4 saves energy and resources(Cr,Mn,Si,Mo).
This material has been used for railcar axle box bearing,changes GCr15SiMn or GCr15 the situation whose use for bearing inner rings. Now the life is one time longer than before. GCr4 is usually for steel balls or running pulley of low loading and simple shape machine shaft.
The equal material of GB/T 18254 GCr4 in different standard.
