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.
