corrosion-resistant tool steel for plastic moulding


SIMOLD tool steel is intended for the manufacture of different moulds for plastics, synthetic resins and rubber moulding. Backing parts of plastic injection moulding tools are made of SIMOLD tool steel alloyed with sulphur, which is added to increase their machinability. SIMOLD steel alloyed with chromium (above 12% Cr) is characterised by its excellent corrosion resistance, placing it in the category of so-called corrosion-resistant tool steels.

The SIMOLD brand of tool steel is installed in a wide variety of tools within an extremely broad industrial spectrum. During use, the steel parts are exposed to pressure, wear and corrosion under certain conditions. Extreme (long) durability confirms the excellent quality of our SIMOLD steel.

To produce SIMOLD steel, we use recycled steel scrap as raw material. The use of scrap results in significantly lower carbon emissions as compared to using iron ore. Owing to this, SIJ brand steels, such as SIMOLD, are proof of the Group's commitment to optimizing its environmental performance.
