Abstract

The invention relates to a method for producing a siderurgical product made of carbon steel having a high copper content, according to which: --a liquid steel having the composition: 0.0005%.ltoreq.1%; 0.5.ltoreq.Cu.ltoreq.10%; 0.ltoreq.Mn.ltoreq.2%; 0.ltoreq.Si.ltoreq.5% 0.ltoreq.Ti.ltoreq.0.5%; 0.ltoreq.Nb.ltoreq.0.5%; 0.ltoreq.Ni.ltoreq.5%; 0.ltoreq.Al.ltoreq.2%, the remainder being iron and impurities, is produced;--said liquid steel is poured directly in the form of a thin strip having a thickness of no more than 10 mm;--the strip is subjected to forced cooling and/or is surrounded by a non-oxidizing atmosphere while having a temperature of more than 1000? C.; --said thin strip is hot rolled at a reduction rate of at least 10%, the temperature at the end of the rolling process being such that all of the copper is still in a solid solution in the ferrite and/or austenite matrix;--and the strip is coiled. The invention also relates to a siderurgical product obtained according to said method.
