| Abstract: | An analysis on macrostructure and microstructure of fracture of cold forging punch pin of GCr15 bearing roller has been made. Reselt showed that the core area of the punch pin existed coarse liquidation carbide and that caused large tensile stress during quenching process which led to crack. |
