<p>The invention relates to a method for producing a steel product, such as a steel plate, having a thickness of 2-60 mm, from a steel billet, which is produced from steel comprising iron and residue contents as well as unavoidable impurities. The steel comprises, as percentages by weight, C: 0,3-0,6%, Al: 1,0-2,5%, and V: 0-0,4%. The method comprises a step, in which to the steel billet is performed annealing for austenitizing at a temperature of 1000-1300°C, more preferably 1050-1220°C. The invention also relates to a steel product, such as a steel plate, having a thickness of 2- 60 mm.</p> |
