Characteristics of steel
Tool steel with high dissolved Cr content (abowe 12%) in the steel matrix. Good corrosion resistant in the hardened condition, good polishability, good machinability, low distorsion, high wear resisatnce and high surface finish. This grade can be produced on request by the process ESR and quenched and tempered condition.
Suitability of steel use
Moulds for corrosive plastic materials such as PVC, recycled polymers etc., moulds for chemically aggressive plastics and plastics containing abrasive fillers, mould inserts, dies and gauges for PVC extrusions, screws and barrels for extruders, moulds for automotive, food, medical and optical industry such as spectacles, compact discs, lenses.
