Continuous treatment of cold-rolled carbon manganese steel

摘要

Cold-rolled, non-microalloyed carbon manganese steel (0.04% to 0.15% C, 0.25% to 0.70% Mn) is preheated at 700 DEG to 1000 DEG F., heated to 1625 DEG to 1725 DEG F., and quenched to 650 DEG to 750 DEG 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.
