In a process for producing high-strength, corrosion-resistant and brittle fracture-resistant prestressing steels, there is a fine grain and/or solid solution and/or particle or precipitation hardening, linked with a thermodynamic treatment and subsequent strain hardening. As strengthening measures are used both a solid solution, fine grain and particle or precipitation hardening with a substantially additive effect. The thermomechanical treatment is performed by a controlled rolling of microalloyed, fine grain-melted steels, whilst excluding martensite formation.
