我厂为德国某公司来样加工压盘,结构如图1所示。德方技术要求如下:材料16MnCr4、表面淬硬层(0.30±0.10)mm、硬度52～58HRC。由于我厂没有与德方16MnCr4相同的材料,经协商采用国产20Cr钢代替。
I plant for a German company sample processing pressure plate, the structure shown in Figure 1. German technical requirements are as follows: Material 16MnCr4, surface hardened layer (0.30 ± 0.10) mm, hardness 52 ~ 58HRC. As I plant does not have the same material with the German side 16MnCr4, after the adoption of domestic 20Cr steel instead.
