DIRECTIONS FOR SUGGESTED USE

Melting temperature: 870 °C

Casting temperature:

80 °C over its melting temperature for continuous casting with sinker thermocouple

100 °C over its melting temperature to cast into ingot-mould and continuous casting

Ingot-mould temperature: 150 °C

Cooling of ingots: quick in lukewarm water (about 40 °C)

Annealing: 620 °C for 20 minutes followed by a quick cooling in hot

water (40 °C min.)

Age hardening: Step 1: solubilization

680 °C for 30 minutes. Cooling quickly in lukewarm water

(about 40 °C).

Step 2: hardening

300 °C for 2 hours. Cooling at room temperature.
