Brief introduction:
DIN 1.2083 steel is chromium alloyed stainless plastic mold steel. It is equivalent to AISI 420 steel. The steel 1.2083 is a major steels for hot pressing in circulation.
1.2083 stainless steel is generally supplied annealed condition with a hardness < 230HB. It can also be delivered ESR and quenched and tempered to 320 HB.
Application:
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.
