At present, the most widely used for stainless steel kitchenware, lamps, motorcycle parts, auto parts and other fine polishing medium hardness of materials, but also for free grinding.
In some cases, in order to get the highest possible sample hardness, the sample may be subjected to heat treatment before polishing.
在某些情况下，为了使试样得到尽可能高的硬度，在抛光前试样可进行热处理。

The influences of the duration of polishing and the coarseness of surfaces on the readings of the brinell hardness measurement of metallic materials are discussed in this paper.
