中文摘要:采用金相、硬度测试和冲击韧度测试等手段,对国内外DC53冷作模具扁钢进行对比研究。结果表明,我国高品质DC53钢在洁净度、碳化物尺寸控制和力学性能等方面均和国外先进水平相当,某些方面甚至好于国外DC53钢。
英文摘要:The steel DC53 at home and abroad was contrasted and studied by OM, hardness test and impact test. The results show that the quality of high-quality steel DC53 of our country is equal to abroad at the respect of cleanliness, size of carbides, mechanical property and so on. Some aspects are even better than the abroad DC53.
