Abstract
Continuous heat treatment procedure in improvable steels, in rod form, subeutectoids with 0.30 to 0.60% carbon, also in those with usual contents of alloy, iron rest and the usual mixtures to improve mechanical material properties (resistance, expansion, or their mutual relationship) by applying rapid heating and subsequent rapid cooling, characterized in that the steel, in its initial state, presents a heterogeneous crystalline structure (pre-eutectoid perlite and ferrite) and through its cross section Total heats up rapidly with a speed, on average, of at least 200ºC/second, preferably at least 300ºC/second through the temperature range above the perlite line (Ac1) at temperatures up to a maximum of 1,300ºC, after which, before a broad carbon diffusion equilibrium cools rapidly with a rate resulting in a stress Almost martensite-free structure.
