Abstract

Steel material containing by weight from 0.4 % to 0.8 % carbon, from 0.5 % to 2.5 % silicon, from 0.3 %
to 2.0 % manganese, from 0.1 % to 1.5 % chromium, and from 0.1 % to 0.5 % molybdenum is hot-rolled to form a plate. The hot-rolled plate 1 is annealed and cold-rolled at a rolling reduction between 10 % and 80 %. The cold-rolled plate is heated at a temperature above Ac3 critical point for a time sufficient to austenitize carbide and annealed.
