Al—N 高速工具钢是一种以碳化物、氮化物等硬化相共同强化的新型钨钼系高速钢。由于 Al、N 的加入,其铸态组织为以 M_6C 为主的细小棒条状共晶碳化物组织结构,实验结果表明,在淬火热处理加热过程中碳化物的溶解量较其它高速钢少,而在回火过程中二次碳化物的析出量又较其它高速钢多。其组织细小均匀,热稳定性和热处理工艺性好,具有良好的综合技术性能和使用性能。适应范围广泛,可用于刃具、模具的制造。 Al-N high-speed tool steel is a kind of carbide, nitride and other hardening co-strengthening of the new tungsten-molybdenum high-speed steel. Due to the addition of Al and N, the as-cast microstructure of the as-cast microstructure was mainly composed of M_6C. The experimental results show that the amount of carbide dissolved in the quenching heat treatment is less than that of other high-speed steels, In the tempering process of secondary carbide precipitation and more than other high-speed steel. Its organization is small and uniform, thermal stability and heat treatment process is good, with good overall technical performance and performance. Adapt to a wide range, can be used for cutting tools, mold manufacturing.
