材料名称: offer.china.alibaba/offer/post/fill_product_info.htm?offerId=421686069&operator=edit&asker=ATC" style="text-decoration: none; color: rgb(34, 34, 34); transition: color 0.3s ease 0s;">高速工具钢棒
牌号:M3标准:AISI●特性及适用范围:
是高碳高钒型高速钢,该钢经济、碳化物细小均匀、韧性高、塑性好,但可磨削性差、易于氧化脱碳。可制作各种类型一般刀具如车刀、刨刀等,适于加工中高强度钢、高温合金等难加工材料,因其磨削性差,不宜制作高精度复杂刀具。
