1、钢材的硬度：金属硬度(Hardness)的代号为H。按硬度试验方法的不同，

●常规表示有布氏（HB）、洛氏（HRC）、维氏（HV）、里氏（HL）硬度等，其中以HB及HRC较为常用。

●HB应用范围较广，HRC适用于表面高硬度材料，如热处理硬度等。两者区别在于 硬度计 之测头不同，布氏硬度计之测头为钢球，而洛氏硬度计之测头为金刚石。

●HV-适用于显微镜分析。维氏硬度(HV)以120kg以内的载荷和顶角为136°的金刚石方形锥压入器压入材料表面，用材料压痕凹坑的表面积除以载荷●HL手提式硬度计，测量方便，利用冲击球头冲击硬度表面后，产生弹跳；利用冲头在距试样表面1mm处的回弹速度与冲击速度的比值计

算硬度，公式：里氏硬度HL=1000×VB（回弹速度）/ VA（冲击速度）。

●目前最常用的便携式 里氏硬度计 用里氏（HL）测量后可以转化为：布氏（HB）、洛氏（HRC）、维氏（HV）、肖氏（HS）硬度。或用里氏原理直接用布氏（HB）

、洛氏（HRC）、维氏（HV）、里氏（HL）、肖氏（HS）测量硬度值。
