Abstract

See full text

A method for producing thermomechanically produced hot strip products having improved mechanical properties is provided. A steel alloy is melted and adjusted so that a recrystallization during hot rolling at greater than 800° C. is suppressed. The melted steel alloy is cast into slab ingots and after being heated to a temperature above Ac3, the slab ingots are hot rolled until they reach a desired degree of deformation and strip thickness. The strip is then cooled to room temperature and is hardened by briefly reheating to a temperature above Ac3 and cooling again. The reheating takes place with a rapid temperature increase of more than 5 K/s and is maintained at the targeted temperature for a period of 0.5 to 60 seconds before cooling to yield the improved mechanical properties.
