Description:
GB/T 18254 GCr18Mo is a kind of high-carbon chromium bearing steel,also a new high abrasive resistance steel. GCr18Mo is equivalent to SKF24 at Swedish standard. Compared with GCr15 and GCr15SiMn, GCr18Mo has more percent of Cr element which improves the abrasive resistance ,and is added Mo element.
GCr18Mo is mainly used to manufacture various bearing inner rings (wall thickness up to 20mm,not the 16mm),making a wide use. Except that, GCr18Mo can also be used to manufacture internal-combustion engine,electric locomotive,machine tool,tractor,steel rolling equipment,driller,steel balls,roller,and axle sleeve of rail truck, mining machine spiale.
