DIN 1.2083/420/S136 alloy tool steel plate hardened tool mould steel material

DIN 1.2083/420/S136 is a chromium alloyed stainless plastic mould steel. 1.2083 has the added benefits of steel that possess good wear resistance and excellent polishability. The combination of these properties provides the steel with an outstanding performance which makes 1.2083 tool steel particularly suitable for moulds for chemically aggressive plastics.

Grades Comparison

Chemical Composition(%)

HEAT TREATMENT:

Annealing:

Heat slowly to 780°C. Slowly cool in furnace.

Hardening:

Pre heat to 600-700°C until heated through. (Austenitizing temperature 1025°C.) Continue heating to the final hardening temperature of 980-1050°.

Tempering:

Heat uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per inch of total thickness. Double tempering is recommended.

Nitriding:
Nitriding of 1.2083 gives it a hard surface which is very resistant to wear and corrosion. Howe ver , the nitrided surface reduces the corrosion resistance. Surface hardness after nitriding at 525°C in ammonia gas will be approximately 1000HV.

Application:
mold plates and inserts for working with chemically aggressive plastics; because of excellent polishing, suitable for optical and medical products

CHARACTER:
low corrosion, high-alloy, low warpage steel for through hardening with excellent properties for mirror polishing as well as good photoetching, good machinability, high wear resistance and high dimensional stability
