DIRECTIONS FOR SUGGESTED USE

Melting range (Solidus – Liquidus): 902 - 910 °C

Casting temperature:

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

100 °C over its Liquidus temperature to cast with centrifugal machines and vacuum machines with

controlled atmosphere

140 °C over its Liquidus temperature to cast in outdoor cylinders with vacuum

Ingot-mould temperature: 150 °C

Cylinders temperature: from 550 °C to 650 °C depending on the machine and

objects dimensions

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

Cooling casted objects: in water after 10 minutes

Annealing: 670 °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 warm water (about

40 °C).

Step 2: hardening

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