A method for the production of high-strength, low-alloy steel with the addition of copper to reduce the formation of a second of the steel ductility minimum is provided in that the steel has a copper content of 0.05% up to 0.5%, in particular in the range of 0.15% brought to 0.35%, and is then poured into a strand or strip casting a strand or a band with a maximum thickness of 130 mm and solidified, wherein the casting speed 4.5 m at least / min, preferably at least 5 m / min, and the strand or strip min followed by continuous rolling or semi-endless rolling is less than 5.8, especially less than 4.5 minutes, it is rolled to the desired final thickness..
