HASCO colour code:


Hardness when supplied:
yellow / white


soft-annealed to max. 241 HB (~810 N/mm²)241

Characteristics

Material properties: Corrosion-resistant mould steel with uniform through-hardness, low distortion, high wear resistance and high compressive strength. Readily machinable. To achieve optimum
eroding surfaces, the material must be highly tempered, which in
turn limits the corrosion resistance.


Uses: Cavity plates and inserts for plastics processing when using corrosive and chemically aggressive plastics and under strongly corroding conditions such as cooling / heating media or wet
climatic conditions.

Remarks

Polishing:                      Possible in the hardened state.
Graining: Possible. With sensitive grain etchings, we recommend prior consultation with the etching shop
Nitriding: Possible using any of the well-known processes. At temperatures above 470°C,the hardness declines and corrosion resistance decreases.
Hardening: At 1000°C – 1050°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: 760°C – 800°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:
50 - 54 HRC
