Abstract
"Process for obtaining easily machinable steels", of the type comprising as improvement elements, sulfur, lead and tellurium, characterized by adding to the mass of steel, the elements of improvement in proportion by weight of, sulfur between 0.25 and 0.35%, lead between 0.08 and 0.35%, selenium between 0.010 and 0.35%, and tellurium between 0.010 and 0.035%, the sum of the selenium and tellurium content being 0.025 to 0.65%.
