What is Shore Hardness Scale? The Complete Guide
SpletThe equation for Rockwell Hardness is , where d is the depth in mm (from the zero load point), and N and h are scale factors that depend on the scale of the test being used (see following section). It is typically used in engineering and metallurgy. Splet常用洛氏硬度试验规范表 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、较薄的工 … カットサロンフジタ
