Wearing member having a pad-welded surface layer high in wear-resistance and heat crack-resistance

摘要

A wearing member having a pad-welded metallic surface layer with high wear and heat crack-resistance and having no irregular hardness is formed by pad-welding deposited steel in a composition range of 0.1 to 0.5 % C, 0.1 to 1.3 % Si, 0.3 to 2.0 % Mn, 1.0 to 5.0 % Cr, 0.5 to 5.0 % Mo and 0.5 to 3.0 % V, the rest being Fe and unavoidable impurities, or further containing one or more of less than 2.0 % W, less than 5.0 % Ni and less than 3.0 % Co.
