DIRECTIONS FOR SUGGESTED USE

Melting temperature: 880 °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 machine

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

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

(40 °C min.), better if with alcohol

Age hardening: Step 1: solubilization

720 °C for 30 minutes. Cooling quickly in lukewarm water

(about 40 °C), better if with alcohol.

Step 2: hardening

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