General descriptions The hardness is one of the important indexes to determine the mechanical properties of the material, and the hardness test is a means which is used to discriminate and determine the quality of metallic materials or components of the product. The so-called hardness is meant the capability of the material which, under a certain condition, is capable to resist the press-in of another matter which will not produce residual deformation itself. The larger the resisting power is, the higher the hardness will be, and vice versa.. In the course of testing the mechanical properties, hardness measurement is the easiest, most economical, and rapidest method, and is also one of the measures which are used to inspect the quality of the product during manufacturing the machine. As the metallic hardness possesses the mutual corresponding relationship with certain other mechanic properties,hence, most metallic materials may approximately infer their other mechanical properties such as strength, fatigue, creep,wearing and internal damages etc. by determining their hardness. Following the daily growing development of the industrial and agricultural production as well as the scientific technology, various kinds of different requirements are also demanded to the hardness tester itself, especially it demands high precision in measurement and test, and may carry out various kinds of hardness test for different kinds of materials. Based upon this, the model HBRVU - 187.5 Brinell, Rockwell and Vickers hardness tester which is produced by our factory possesses the conditions which fulfill all the above mentioned requirements.
