Abstract (en)

[origin: EP0131091A2] In the material with mainly graphite carbon, the graphite is predominantly in the form of a vermicular graphite precipitation, preferably with a residual magnesium content of 0.01 to 0.04 % by weight. In a process for producing the material, a treatment additive of pure magnesium is added to the molten iron base, and even sulphur- rich molten iron bases can be processed.
