ABSTRACT OF THE DISCLOSURE A rolled steel product emerging from a hot rolling mill is cooled by means of a fluid so as to produce martensitic and/or bainitic quenching of the surface layer of all or part of the product. The non-quenched portion remains at a temperature sufficient to cause tempering of the martensite and/or bainite in the surface layer to take place during subsequent air cooling. According to the invention, the maximum temperature of the tempered surface of the product after quenching is 600 to 730°C. The method is of utility in treating concrete-reinforcing rod, wire rod, steel sheet, and steel sections.
