表面洛氏硬度计 R(D)-45A1

    R(D)-45A1型表面洛氏硬度计是一种轻负荷洛氏硬度试验仪器。施加试验力的速度由缓冲器来调节，试验力的变换采用变荷手轮的旋转而获得，所以该机具有操作简便、性能稳定、测试速度快、试验力小、留下微小的压痕等特点，在大多数情况下不影响试件的使用。该硬度计适用硬质合金、渗碳钢、淬火钢、硬铸铁及软钢、铝合金、铜合金和可锻铸铁的硬度的测定。

R(D)-45A1 the surface Rockwell hardness is a light load Rockwell hardness test equipment.Test force imposed by the speed of the buffer to adjust, the test force of the transformation could be changed by the hand wheel getting,so the hardness tester is simple, stable performance, the test speed of the fast, the test force of the small, leaving tiny indentation, and other characteristics, in most cases do not affect the use of samples.

That degree of hardness accounts to be applicable to the black metals and have the Rockwell surname degree of hardness measurement of the color metals.It is extensive to be applocable to factory car with calculate the section.
