- the German patent DE 242 658 C discloses a method for producing a free-cutting steel that is readily thermoformable, with a steel with a basic composition of a maximum of one percent carbon, 0.6 to 1.65 percent manganese and sulfur, tellurium, selenium and silicon, the rest at least ninety percent iron, is melted, the content of tellurium and / or selenium being limited to 0.02 to 0.10 percent tellurium and / or selenium, the sulfur content being controlled in such a way that the content of tellurium and / or Selenium does not exceed by weight, but the number of sulfur atoms is measured to be higher than that of selenium and tellurium atoms, and the silicon content is limited to a maximum of 0.05 percent.
- the German patent application DE 2 152 013 A1 discloses a process for the production of non-alloyed, medium- or high-carbon steels or alloyed steels which contain tellurium, with the others in the molten steel

- the task is in a method for producing a
- the claimed method can effectively reduce the size of the pickling pits that occur when the steel material is pickled.
- the internally pressurized component is a machined component.
- the machined component is provided with a zinc-nickel coating, for example.
- the component is, for example, a forged part.
- the steel material is, for example, a ferritic-pearlitic steel material, a heat-treatable steel or a case-hardening steel.
