  • Effects of Duplex Structure in GCr18Mo Bearing

    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.
