HASCO colour code:


Hardness when supplied:
red


soft-annealed to max. 220 HB (~770 N/mm²)

Characteristics

Material properties:

High-alloy hot-work steel with high resistance to changing
temperatures and good heat resistance.High thermal
conductivity and toughness.


Uses:

Cavity plates and inserts for the plastics and die-casting
industry (e.g. where nitriding is to be carried out with
high core strength).

Remarks

Polishing:                            Durch homogenes Gefüge für Polituren gut geeignet. Für Hochglanzpolituren 1.2343 in ESU- Güte verwenden.
Graining: Gut geeignet, für feine Strukturen 1.2343 in ESU- Güte verwenden.
Nitriding: Erhöht die Verschleißfestigkeit und verhindert ein verkleben von Einsatz und Artikel.
Hardening: Bei 1000°C – 1030°C.
Details can be taken from the time-temperature conversion and tempering charts. The most suitable heat treatment for the relevant work piece should be fixed by the hardening shop. The hardness should be specified by the hardening shop and checked on delivery.
Soft annealing: 800°C – 840°C, approx. 4 h
Stress-relief
annealing:
To eliminate residual stress after coarse machining at
approx. 600°C – 650°C, approx. 4 h with slow heating and furnace cooling.
Normal
working hardness:
30 - 53 HRC
