锻模是金属热态变形的工具。由于型窝形状复杂,并且承受冲击载荷,在模体内造成各种各样的复杂应力(拉伸、压缩和弯曲等),工作表面还要受到锻件的反复加热,因此锻模钢无论机械性能(强度和冲击韧性)、抗磨损性、淬透性、导热性及切削加工性方面都必须满足较高的要求。锻模钢一般均保持近似于结构钢,并属于亚共析或接近于共析钢。其中含碳量不高,加入一定数量的多种
Forging dies are tools for hot deformation of metals. Due to the complex shape of the pocket and its impact loading, various complex stresses (tensile, compressive and bending, etc.) are caused in the mold body and the working surface is also subject to repeated heating of the forgings, so that forging dies, regardless of their mechanical properties Strength and impact toughness), wear resistance, hardenability, thermal conductivity and machinability must meet the higher requirements. Forged steel generally remain similar to the structural steel, and belong to the sub-eutectoid or close to eutectoid steel. Which carbon content is not high, adding a certain amount of a variety
