常用HV≈HB≈HRC硬度对照表，一目了然材料 搜狐
Jan 3, 2020 hrc标尺的使用范围是20~70hrc。 当硬度值小于20hrc时，因为压头的圆锥部分压入太多，灵敏度下降，这时应改用hrb标尺； 当试样硬度大于67hrc时，压头尖端承受的压力过大，金刚石容易损坏，压头寿命会大大缩短，因此一般应改用hra标尺。 洛氏硬度试验操作简便、迅速、压痕小，可测试成品表面及较硬 Jul 31, 2016 1、HB：以一定的载荷（一般3000kg）把一定大小（直径一般为10mm）的淬硬钢球压入材料表面，保持一段时间，去载后，负荷与其压痕面积之比值，即为 布氏硬度 值（HB），单位为公斤力/mm2 (N/mm2)，是布氏硬度。 2、HRC：是采用150kg载荷和钻石锥压入器求得的硬度，用于硬度极高的材料（如淬火钢等），是 洛氏硬度 中的一种标准。 机械设计，HB240260相当于HRC多少 百度知道
