几年来,我们通过试验和现场实践,对W6Mo5Cr4V2A1新型高速钢热处理工艺进行了初步研究,提出一些粗浅看法,供兄弟单位参考。一、W6Mo5Cr4 V 2Al钢热处理特点 W6Mo5Cr4V2Al钢是以W6Mo5Cr4V2为基,增碳加铝后获得的,其化学成分见表1。与W18Cr4V钢比,增加了含碳量和含钒量、减少了含钨量、新加入了钼和铝。由于高碳、钼和铝的影响,使W6MoSCr4V2Al钢的热处理特点不同于W18Cr4V钢。高碳的影响高碳增加钢的奥氏体晶粒粗化倾向,降低钢的开始熔化温度,使钢易
Over the past few years, we conducted a preliminary study on the heat treatment process of W6Mo5Cr4V2A1 new high-speed steel through experiments and field practices, and put forward some superficial views for the reference of our brother units. First, W6Mo5Cr4 V 2Al steel heat treatment characteristics W6Mo5Cr4V2Al steel is based on W6Mo5Cr4V2, obtained by carbon plus aluminum, the chemical composition shown in Table 1. Compared with W18Cr4V steel, increased carbon content and vanadium content, reducing the amount of tungsten, the new addition of molybdenum and aluminum. Due to the influence of high carbon, molybdenum and aluminum, the heat treatment characteristics of W6MoSCr4V2Al steel are different from those of W18Cr4V steel. The effect of high carbon High carbon increases austenite grain coarsening tendency of steel, reducing the initial melting temperature of steel, making steel easy
