This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness.

4、弹簧硬度（HV）：是用一块重量为98.07N（10Kgf）、面积为垂直于试样表面的平方，施加在试样上，是用量压结构体硬度测量，简称VHN （半个重量N表示），单位Kgf/mm2。

Vickers hardness test is a micro testing method used for some specified cases. Sometimes it becomes necessary to change the hardness value from one scale to another. Here we compare the Vickers hardness method with the Rockwell method and their conversion charts. I. What is Vickers Hardness? The Vickers hardness test is represented by (HV).

(1)以相同硬度的物体对努氏维氏两种压头具有相等的抗力为依据，分别对维氏努氏两种压头在加载荷下的应力进行推导，再根据σHK=σHV得出：HV=0.968HK。 本公式是在低载荷下测得，误差比较大。 此外在硬度值大于HV900时此公式误差很大，失去参考价值。 经实际数据验证，该公式的最大相对换算误差为0.75%，具有较高的参考价值。 2. 洛氏硬度 与维氏硬度的换算. 此公式用我国公布的黑色金属硬度标准数据进行换算，其HRC误差基本上在±0.4HRC 范围内，其最大误差 …

A variety of hardness -testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.

维氏硬度 (HV)是以一定的载荷和相对面夹角为136°的方锥形金刚石压入器压入材料表面，保持规定时间后，测量压痕对角线长度，用载荷值除以材料压痕凹坑的表面积的值，单位为N/mm 2。 [6] 在实际测量中，并不需要进行计算，而是根据所测d值，直接进行查表得到所测硬度值。 [1] 维氏硬度是英国史密斯（Robert L. Smith）和塞德兰德（George E. Sandland）于1921年在维克斯公司（Vickers Ltd）提出的。 表示材料硬度的一种标准。 以49.03~980.7N的负荷，将相对面夹角 …
