金属模具材料的种类繁多,为满足各种用途的需要,本文简介各类材料的特点。 1.冲压金属模具材料的种类及特点 在冷冲压用的金属模具材料中,以前通用钢种的化学成分和它们的诸性能比较如表1所示。一般来说,YC3→SGT→SLD→YXMI→XVCS逐渐高性能化。根据不同的被加工材料及生产量,金属模具材料的选择如表2所示。与此相对,由于最近需要的多 Mold a wide range of materials, in order to meet the needs of various uses, this article describes the characteristics of various types of materials. 1. Stamping metal mold material types and characteristics In the cold stamping metal mold material, the chemical composition of the previous general-purpose steel and their performance as shown in Table 1. In general, YC3 → SGT → SLD → YXMI → XVCS are gradually becoming more and more advanced. According to different materials and the amount of processed material, the choice of metal mold materials are shown in Table 2. In contrast, due to the recent need more
