由于锻模的体积和重量一般都比较大,对于它的性能检验往往只是测试硬度。锻模的硬度范围多在HRC37～45(淬火时正常硬度为HRC56～60) 。笔者从生产实践中得出:锻模
Due to the size and weight of the forging die are generally relatively large, for its performance test is often just the test hardness. Forging die hardness range HRC37 ~ 45 (normal hardness when quenching HRC56 ~ 60). The author draws from the production practice: Forging die
