  1. As assembly plates, and also anvils, etc. measures of hardness for Brinell (НВ), applied to calibration (checking) of devices well are suitable for measurement of hardness of metal: steel tiles of the set hardness with one polished (non-working) and one polished plainly - parallel surfaces. After the working polished surface is used (it is covered with very superficial prints of balls), measures become unsuitable to application for the intended purpose and jump out scrap metal. Some such used measures with a hardness about 400 НВ (for steel very high hardness) and well ground non-working surface, I "lifted" literally from a floor and I use for construction of models (see, for example, photo on the previous page). Possible sources of measures of hardness - all industries where devices are applied to measurement of hardness of metal: various laboratories of mechanical tests of metals other.
