HASCO colour code:
Flat steel:


Hardness when supplied:
black / red
black


soft-annealed to max. 255 HB (~860 N/mm²)

Characteristics

Material properties:

Versatile cold-work steel, highly chrome-alloyed steel, good
dimensional stability and toughness combined with high
compressive strength. For good eroding properties, secondary
hardening is recommended.


Uses:

Compression moulding and injection moulding tools for
reinforced plastics. Cutting, punching and thermoforming
tools and other applications where a high level of toughness
is required.

Remarks

 
Polishing:                       Possible in the hardened state.
Graining: Not usual.
Nitriding: Only recommended after secondary hardening.
Hardening: 1000°C – 1050°C,
Details can be taken from the time-temperature conversion and tempering
charts. The most suitable heat treatment for the relevant workpiece should be fixed
by the hardening shop. The hardness should be specified by the hardening shop
and checked on delivery.
Soft annealing: 820°C – 850°C, ca. 4 Std.
Stress-relief
annealing:
To eliminate residual stress after coarse machining atapprox. 600°C – 650°C, approx. 4 h with slow heating and furnace cooling.
Normal
working hardness:
58 - 62 HRC
