Abstract

A hot rolled armor plate is made of a low carbon, low alloy steel containing carbonitride-forming vanadium as precipitation hardening element. A novel hot rolled armor plate consists of a steel of composition (by wt.) 0.15-0.20% C, 0.10-0.50% Si, 0.70-1.70% Mn, less than 0.02% P, less than 0.005% S, less than 0.01% N, 0.009-0.10% Al, 0.50-1.00% Cr, 0.20-0.70% Mo, 1.00-2.50% Ni, 0.05-0.25% V, balan Fe and impurities. An Independent claim is also included for production of the above armor plate by hot rolling, double austenitizing at 880-980 degrees C, quenching and tempering at 150-550 degrees C.
