Abstract
The wear properties of steels against a soil were studied by using normalized carbon steels having different amount of carbon. Hirose river sand having 24-48 meshes was used as a soil.
In the case of the running velocity is constant, the effects of humidities of soil, cutting angles and cutting resistance upon the durability of wear of low carbon steels were clarified by a solid diagram. And the respective relationships between the humidities of soil, the amount of wear of metals and the amount of carbon content of steels were clarified systematically by ternary solid diagram.
