The improvement of the Mechanical properties of the low Carbon steel and increasing its strength, was the goal of some heat treatment technologies developed in the last twenty years. One of these technologies is the Rapid Heat Treatment (RHT), by which the strength of steel increases with the crystalline grain size decrease obtained from the rapidity of austenitizing, and more strength increase may be obtained, if the action of austenitizing is followed by rapid cooling or quenching, but in this case, ductility will decrease simultaneously by increasing the cooling rate. Another mechanical properties improving heat treatment, is the Intercritical Heat Treatment (IHT), by which the ferrite-pearlite structure of low Carbon steel transforms to Dual-Phase structure of ferrite and martensite resulting increase in strength, while a great deal of its ductility is restored. Authors in this paper report about their experiments carried out on a low Carbon-steel, trying to get the advantages of the two above mentioned technologies, by subjecting the formerly rapid heat treated steel, to intercritical heat treatment,. Applying this treatment on the steel in different temperatures inside the intercritical zone, remarkable results were obtained and reported.
