9Mn2V钢板#合金工具钢9Mn2V耐磨钢板
Characteristics and scope of application: 9 mn2v tool steel, cold work die steel is better than carbon tool steel has good comprehensive mechanical properties of low alloy tool. Has the high hardness and wear resistance, hardenability is better also, quenching deformation small. Is suitable for making small cold work mould, especially for making demands little deformation, wear resistance of high precision measuring tools (such as model, block gauge, gauge, etc.) and precision screw, grinding spindle. 9 mn2v tool steel chemical composition
9Mn2V工具钢 特性及适用范围：冷作模具钢，是具有比碳素工具钢有较好的综合机械性能的低合金工具。具有较高的硬度和耐磨性，淬透性也较好，淬火时变形小。适于制作小型冷作模具，特别适用制作各种要求变形小、耐磨性高的精密量具(如样板、块规、量规等) 以及精密丝杆、磨床主轴等。
