ABSTRACT:
Cold-rolled, non-microalloyed carbon manganese steel (0.04% to 0.15% C, 0.25% to 0.70% Mn) is preheated at 700.degree. to 1000.degree. F., heated to 1625.degree. to 1725.degree. F., and quenched to 650.degree. to 750.degree. F. in a continuous process to develop minimum yield strength of 40,000 psi, minimum tensile strength of 50,000 psi, and 22% minimum elongation.
