Product Description

To control various industrial hardness testers, it is important to verity all related factors, including indenters, staic and dynamic loads, indentation measurment, and sample pieces.

Hardness blocks allow overall control of these complicated factors in the field. Therfore, it is imperative that a uniform surface hardness is displayed by all our test blocks, that the main facors of secular change are eliminated and, if possible, that the characteristics of their materials are similar to those of materials in practical use.

Yamamoto company, which was established in 1939 by Shoichi Yamamoto, is the first dedicated manufacturer of standard test blocks in Japan, and has maintained its reputation as the best and the foremost company in this field.
