PROCESS FOR PRODUCING COLD ROLLED HIGH TENSILE STRENGTH STEEL PLATE HA VING EXCELLENT FLANGE PRESSED DRAWABILITY

摘要

PURPOSE:To produce steel of high tensile strength not less than 50kg/mm<2> and good cold workability by decreasing the amount of C, controlling the amount of Mn at a comparatively low value, adding Si, Ti, Mo in balanced amounts, and adjusting conditions for hot rolling.
