1、万璽氏换算表，洛氏换算表硬度符号：为避免混淆用不同冲击装置测量得到的里氏值;由里氏值换算出的其它硬度值与其它各种方法测得的其它各种硬度值;推荐使用下列符号：612 LD341 HBLD354 HVL硬度 的里 氏值Ld：用冲击装置D测得的里氏值HBLD:换算成布氏硬度的里氏值HVLd：换算成维氏硬度的里氏值hrcld :换算成洛 氏35.9HRCLd扩展换算表的建立：对于特殊用途，使用者可扩充各个换算表，但必须注意下列各点：必须使用标准冲击装置D校验里氏硬度测试仪的正确读数.必须用相应测量范围的试块校验各种静态测试仪的性能.相关硬度值的测试点应尽可能接近，为得到分别用静、动态方法测得的一对可比
