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,other | ||
characteristics, in most cases do not affect the use of samples. | ||
That degree of hardness accounts to be applicable to the black metalshave the rockwell | ||
surname degree of hardness measurement of the color metals.It is extensive to be applocable to | ||
factory car with calculate the section. | ||
