塑料件金属模用钢的简介塑料件金属模用钢的划分塑料件金属模用钢的种类可划分为预硬系和淬、回火系;还可以根据使用要求,按硬度等级划分。预硬系钢是按硬度,调质成Rc10、20、30、40、四个档次进行供货的,能用于金属模的直接雕刻加工。在目前这种用于直接雕模的预硬系钢的加工硬度上限是Rc43。淬、回火钢是在退火状态下供货的。模具加工后,要进行热处理(淬、回火)以达到相应用途的设计硬度,而在热处理
Plastic parts Metal mold steel Brief introduction Plastic parts Metal mold Steel division Plastic parts Metal mold The type of steel can be divided into pre-hardened and quenched and tempered; can also be used according to requirements, divided by the hardness level. Pre-hard steel is based on hardness, quenched and tempered into Rc10,20,30,40, four grades for delivery, can be used for direct engraving of metal molds. In the current pre-hardened steels for direct engraving, the upper limit of processing hardness is Rc43. Quenched, tempered steel is supplied in an annealed condition. Mold processing, to be heat treatment (quenching and tempering) to achieve the hardness of the corresponding design, and in the heat treatment
