<p>The specification discloses a completely automated method and apparatus for producing high tensile steel, of a controlled, predetermined U.T.S. and cross sectional area, from low to medium carbon steel by subjecting the steel to substantial elongation while simultaneously substantially heating and immediately thereafter rapidly quenching the steel, and while continually moving the steel relative to the heating and quenching means employed. The steel is heated to a temperature above its austenite conversion temperature. Greater elongation produces greater ultimate tensile strength, as much as more than twice as great as the starting ultimate tensile strength, and elongations approaching 200 percent have been effected.</p> |
