To obtain a wear resistant steel for a cylinder sliding member in which scuffing resistance is stabilized by specifying the contents of C, Si, Mn, Cr, P and S in the compsn. of the steel.
A compsn. of a wear resistant steel is composed of, by weight, ≤2.2% C, ≤1.2% Si, ≤0.2% Mn, ≤16% Cr, ≤0.08% P, ≥0.15% Si, ≤2.0% other components, and the balance substantial Fe. In this compsn, in the case the content of Cr is regulated to ≤6.0%, its mechanical properties are made satisfactory. In this steel compsn., the preferable ranges are regulated to 0.25 to 2.0% C, 0.20 to 1.20% Si, 0.40 to 1.20% Mn, 0.80 to 5.50% Cr, ≤0.05% P, 0.20 to 0.50% S, and ≤1.0% other components. In this wear resistant steel, preferably, the surface is subjected to electrolytic immersing treatment, or, after the electric immersing treatment, it is subjected to baking treatment of molybdenum dioxide. This steel can be adopted to either or both sliding faces of the inner ring and outer ring of a ring spring.
