Abstract

PURPOSE: To manufacture an age hardening structural steel having improved weldability as a material for a large-sized metal mold by adding specified percentages of C, Si, Mn, Ni, Mo, Cu and Al to Fe.
CONSTITUTION: This age hardening structural steel consists of, by weight, 0.05W0.20% C, 0.1W2.0% Si, 0.5W2.1% Mn, 0.5W1.4% Ni, 0.2W0.6% Mo, 0.5W2.0% Cu, 0.4W1.5% Al and the balance Fe with inevitable impurities or further contains one or more among ≤0.3% S, ≤0.5% Pb, ≤0.5% Se, ≤0.5% Te and ≤0.5% Bi. Though the steel is less expensive than a conventional steel used as a material for a large-sized metal mold, it has improved weldability and can be used as welded because the welding does not differ in hardness from the base metal.
