Abstract

PURPOSE: To obtain a wear resistant cast steel having enhanced internal hardness without deteriorating the impact resistance by soaking and holding a steel contg. a restricted amount of C, Si, Mn, Ni, C, Ti, B, P, S and Al at a low temp., followed by quench hardening and tempering at a low temp.
CONSTITUTION: A steel consisting of 0.20W0.35% C, 1.00W1.30% Si, 1.00W1.50% Mn, 0.80W1.50% Ni, 0.50W1.00% Cr, 0.03W0.08% Ti, 0.002W0.006% B, ≤0.025% P, ≤0.015% S, 0.08W0.12% Al and the balance Fe is cast. This steel is soaked and held at a relatively low temp. such as 850W900°C, and it is subjected to quench hardening and tempering at a low temp. such as about 100W300°C. By this treatment a wear resistant cast steel capable of enhancing the surface hardness and the internal hardness of a product without deteriorating the impact resistance is obtd. while saving expensive elements.
