Claim:
A method to obtain a steel alloy comprising at least a first step wherein a determinate quantity of manganese steel scrap or carbon steel scrap is melted in a furnace in order to define a metal bath, a possible second step wherein, in order to deoxidize said metal bath, a determinate percentage weight of aluminum is added to said metal bath during tapping into the ladle, and a third step wherein said metal bath is cast at a determinate casting temperature, wherein, between said second step and said third step, at least a fourth step is also provided during tapping into the ladle wherein a second determinate percentage weight of nitrogen is added to said metal bath, and wherein between said second step and said third step, in addition to said fourth step, a fifth step is provided when tapping is completed wherein a third percentage weight of titanium is added to said metal bath in the ladle, comprised between about 0.3% and about 5% and once the titanium has been introduced into the metal bath, an injection of argon gas is performed, wherein before said third step of casting, a further injection of argon gas under the slag is performed in the metal bath in the ladle.
