A method for producing a steel product having excellent mechanical properties, such as a steel pipe, the method including cold forming (1, 2), whereby a strain hardened structure is formed in the steel, characterized in that the method also comprises the following steps: steel having a strain hardened structure is heated very rapidly, i.e. at a rate of HR ≥ 100°C/s to a temperature of Ac3 ± 100 °C, without soft annealing prior to the rapid heating - the heated steel is cooled such that the resulting microstructure formed in the steel product will comprise at least 30% martensite and/or bainite in percentages by volume, whereby the steel product produced by the method comprises in percentages by weight: C: 0.05-0.25 % Si: 0 - 2.5 % Mn: 0.8 - 3.0 % Al: 0 - 2.5 % Mo: <1.5 %, preferably 0.1-0.8 % Cr: <1.5 %, preferably 0.2 - 1.5 % Cu <1.00 % Ti: < 0.15 % Nb: < 0.09 % V: < 0.17 % Ni: 0 - 0.07 % preferably 0.015 % < Ti+Nb+V < 0.22 % the balance being iron Fe and unavoidable residuals such that the hardenability index DI of the steel product is at least 3mm, preferably at least 15mm, or whereby the steel product produced by the method comprises in percentages by weight: C: 0.10-0.40 %, Si: 0 - 2.5 % Mn: 0.2 - 3.0 % Al: 0 - 2.5 % Cu 0 - 1.0% B: 0.0005 - 0.009 % Cr 0 - 1.5 % Mo 0 - 1.5 % Ti: < 0.15 % Nb: < 0.09 % V: < 0.17 % Ni: 0 - 0.07 % the balance being iron Fe and unavoidable residuals such that the hardenability index DI of the steel product is at least 3mm, preferably at least 15mm. steel having a strain hardened structure is heated very rapidly, i.e. at a rate of HR ≥ 100°C/s to a temperature of Ac3 ± 100 °C, without soft annealing prior to the rapid heating - the heated steel is cooled such that the resulting microstructure formed in the steel product will comprise at least 30% martensite and/or bainite in percentages by volume, whereby the steel product produced by the method comprises in percentages by weight: C: 0.05-0.25 % Si: 0 - 2.5 % Mn: 0.8 - 3.0 % Al: 0 - 2.5 % Mo: <1.5 %, preferably 0.1-0.8 % Cr: <1.5 %, preferably 0.2 - 1.5 % Cu <1.00 % Ti: < 0.15 % Nb: < 0.09 % V: < 0.17 % Ni: 0 - 0.07 % preferably 0.015 % < Ti+Nb+V < 0.22 % the balance being iron Fe and unavoidable residuals such that the hardenability index DI of the steel product is at least 3mm, preferably at least 15mm, - the heated steel is cooled such that the resulting microstructure formed in the steel product will comprise at least 30% martensite and/or bainite in percentages by volume, whereby the steel product produced by the method comprises in percentages by weight: C: 0.05-0.25 % Si: 0 - 2.5 % Mn: 0.8 - 3.0 % Al: 0 - 2.5 % Mo: <1.5 %, preferably 0.1-0.8 % Cr: <1.5 %, preferably 0.2 - 1.5 % Cu <1.00 % Ti: < 0.15 % Nb: < 0.09 % V: < 0.17 % Ni: 0 - 0.07 % preferably 0.015 % < Ti+Nb+V < 0.22 % the balance being iron Fe and unavoidable residuals such that the hardenability index DI of the steel product is at least 3mm, preferably at least 15mm, or whereby the steel product produced by the method comprises in percentages by weight: C: 0.10-0.40 %, Si: 0 - 2.5 % Mn: 0.2 - 3.0 % Al: 0 - 2.5 % Cu 0 - 1.0% B: 0.0005 - 0.009 % Cr 0 - 1.5 % Mo 0 - 1.5 % Ti: < 0.15 % Nb: < 0.09 % V: < 0.17 % Ni: 0 - 0.07 % the balance being iron Fe and unavoidable residuals such that the hardenability index DI of the steel product is at least 3mm, preferably at least 15mm.
