摘要

A method of producing steel plate having a low yield ratio and high strength and a dual-phase mixed microstructure of ferrite and second-phase carbide comprises heating to at least 950°C low-carbon slab steel having 0.30% or less carbon, 0.05 to 0.60% silicon, 0.5 to 2.5% manganese, and 0.01 to 0.10% aluminum as the basic components, with the balance being iron and unavoidable impurities, or low-carbon low-alloy slab steel comprising in addition to the above basic components one or more elements selected from copper, nickel, chromium, molybdenum, niobium, vanadium, titanium, boron and calcium, hot rolling it, reheating it and tempering it.
