DIRECTIONS FOR SUGGESTED USE

Melting temperature: 900 °C

Casting temperature:

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

100 °C over its melting temperature to cast with centrifugal machines.

120 °C over its melting temperature to cast in vacuum machines with controlled atmosphere.

140 °C over its melting 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.

Cooling casted objects (with stone): in water after 30/40 minutes.

Annealing: 650 °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
