MANUFACTURE OF ALUMINUM KILLED LOW MANGANESE DEEP DRAWING STEEL

摘要

A process of making aluminum killed, low manganese, deep drawing steel having a manganese content of up to 0.24%. The steel is hot rolled to hot band, cold rolled to final gauge, annealed and subjected to a small amount of temper rolling. In the annealing step, the steel is box annealed in coil form in such a manner that a coil cold spot temperature of at least about 1100° F. (593° C.) and below about 1250. degree. F. (677° C.) is achieved.
