Abstract

Process for improving the surface of the shape molding machinery based on non-alloy and low alloy steel by means of preventing the nitreating of niteria on the surface of the cast iron when nitrogenated harnessing agents are used in the molding material, characterized by the fact that an agent containing one or more elements with a high affinity for nitrogen, for example titanium, zirconium selenium or tantalum, is added to the molten steel, before casting in the shell molds or during it, or it is composed of one or several such elements.
