high-alloy.

high-quality polishable property.

pre-toughened tool steel.

APPLICATION:

molds for processing corrosive plastics.

TREATMENT BY

good suitability for:

Polishing
is possible:

Etching, EDM

Nitriding:
reduces the corrosion resistance

 

HEAT TREATMENT:

already pre-toughened; usually, no heat treatment is required.

Soft annealing:
760 to 800 °C for about 4 to 5 hours; slow controlled cooling of 10 to 20 °C per hour to about 650 °C; further cooling in air, max. 230 HB

Hardening:
1030 to 1050 °C.
15 to 30 minutes keeping curing temperature.
quenching in water/oil.
obtainable hardness: 49 HRC.

Tempering:
Slow heating to tempering temperature immediately after hardening. Minimum time in the furnace: 1 hour per 20 mm part thickness
