Abstract
A process for making desired low (LH) hardenability steels in an electric arc or, induction furnace, which is loaded with metal charge consisting of iron, carbon, alloy, scrap with a specified maximum content of manganese, silicon, chrome, nickel and copper, providing for the final content of each of them of not more than 0.1 weight % followed by carburization in a ladle or ladle furnace, the melt then deoxidized in the ladle or ladle furnace with aluminum (1.0-2.3 kg/t), titanium or vanadium in order to achieve the desired low hardenability DI. The invention makes it possible to obtain better mechanical properties and stable hardenability characterized by the particular desired DI.
