| Abstract: | The requirements of impact at low temperature for S355J2G3 steel forgings are very strict,and the surface cracks are not controlled easily.By means of improving the purity of molten steel,adopting the overcooling measurement for steel ingot and enhancing the cooling effect of the normalizing,the qualified S355J2G3 steel forging has been manufactured. |
