摘　　要：对H13加入微量合金元素Nb热作模具钢锻造模块的显微组织和机械性能进行了研究,结果表明:采用EAF+LF+VD+ESR工艺可以生产出高纯净度的H13Nb钢。不淬回火处理及淬回火处理后的H13Nb钢都拥有优良的横向冲击及拉伸性能,同时显微组织均匀,与相同工艺生产的H13钢相比较冲击韧性有所提高,显微组织差别不大。In this paper the H13 adding alloy elements of Nb hot forging microstructure and mechanical properties of die steel were studied. The results showed that the EAF＋LF＋VD＋ESR process can produce high-purity steel H13Nb. No quenching tempering treatment and quenching tempering of H13Nb steel with transverse impact and excellent tensile properties. At the same time homogeneous microstructure, compared with the same H13 steel production process impact toughness increased, little difference in microstructure.
