ABSTRACT:
In a continuous heat-treatment process, cold-rolled steel strip having a thickness of 0.05 to 1 mm, e.g. for producing tin plate, is heated to 650.degree.-850.degree. C. and held in this temperature range for more than 1 s. The strip is then quenched for less than 12 seconds in an aqueous bath at above 75.degree. C., the strip emerging at below 550.degree. C. Temperatures, times, and subsequent steps such as overaging and final cooling are chosen depending on the hardness desired.
