摘要
对比研究了新型冷作模具钢SDC55和进口模具钢DC53、SLD及ASSAB88的抗弯曲性能和耐磨损性能。在电子万能试验机上对实验钢的抗弯曲性能进行了测试,并在M-200磨损仪上研究了其耐磨性能。利用超景深三维显微系统研究了实验钢磨损后的磨痕,并对其进行了金相观察。利用JMat-Pro软件对4种实验钢的组织进行了计算。通过对比研究发现,与进口对比钢相比,新型冷作模具钢SDC55的抗弯曲性能最好,并且其耐磨损性能好于SLD钢。
The bending strength and wear resisting properties of a newly developed cold working die steel SDC55 and the imported ones DC53 ,SLD and ASSAB88 were compared. The property of bending strength and wear resisting on tested steels were investigated by using electric universal testing machine and M-200 abrasion instrument respectively. The grinding crack and microstructure were studied by means of Ultra-depth three-dimensional microscopy system and optical microscope. The microstructures of these four tested steels were computed by the software JMat-Pro. Results showed in comparison with the imported steel, the bending strength of the SDC55 was the best. In addition, the wear resisting property of newly developed steel SDC55 was better than that of SLD steel.
