A method for producing a high strength steel piece by heat treating the piece on an equipment in order to obtain desired mechanical properties is provided. The heat treatment includes a final treatment including at least an overaging for which it is possible to calculate two final treatment parameters OAP1 and OAP2 depending at least on the at least one operating point. The method includes the steps of determining a minimum first final treatment parameter OAP1 min and a maximum second final treatment parameter OAP2 max respectively, in order to obtain the desired mechanical properties and determining at least the operating points of the overaging section such that the first final treatment parameter OAP1 and the second final treatment parameter OAP2 resulting from operating points are such that: OAP1≥OAP1 min and OAP2 ≤ OAP2 max. The method further includes heat treating the piece on the equipment running according to the determined operating points. |
