Zusammenfassung:	The invention relates to a method for producing a threaded part (10), comprising the following steps: a. Rolling a threaded wire made of low-alloy carbon steel to produce a threaded part (10) with a thread; b. Heating the entire threaded part (10) under a carbon and/or nitrogen atmosphere to an austenitizing temperature and maintaining this temperature; c. Quenching the entire threaded part (10) to a bainite temperature and maintaining the bainite temperature until the threaded part has a bainite-containing structure on its cross section. The invention is characterized in that the threaded part (10) is subsequently locally hardened at its end (22) by heating the end (22) to an austenitizing temperature and quenching the threaded part (10) to a temperature below the martensite starting temperature (Ms). 本发明涉及一种用于制造螺纹件(10)的方法，所述方法包括以下步骤：a.轧制由低合金碳钢制成的螺纹线材制造具有螺纹的螺纹件(10)；b.在碳气氛和/或氮气氛下将整个螺纹件(10)加热到奥氏体化温度并保持该温度；c.将整个螺纹件(10)淬火到贝氏体化温度并保持该贝氏体化温度直到所述螺纹件在其横截面上具有含贝氏体结构。本发明的特征在于，随后通过将端部(22)加热到奥氏体化温度并将所述螺纹件(10)淬火到低于马氏体起始温度(
