摘　　要：通过分析有机物切割刀具用钢的使用性能及设计要求,设计并生产了一种新型有机物切削刀具用的高碳低合金钢,采用了粒子相钉扎晶界细化晶粒及低温二次硬化技术,使该钢的硬度可达68～72HRC,并有一定韧性与之匹配。该钢已经应用在卷烟厂制作解把刀、打叶刀、切丝刀等刀具,以及其他有机物切削刀具,使用性能及寿命均高于同类型钢种。Based on the analysis of performance and design requirements for organic matter cutting tool steel,a new type cutting tool steel with high carbon and low alloy was produced.Using secondary phase refining grain boundary in combination with low-temperature secondary hardening process,68-72 HRC of hardness was obtained,balanced with a certain toughness.The steel has been applied to tobacco stem untwining tool and blade-vein split tool,as well as other organic matter cutting tool,both the performance and life of the developed steel are higher than those of the same type steels,
