Hardness (as cast): 192 HV

Hardness (after annealing): 190 HV

Hardness (after age hardening): 307 HV

DIRECTIONS FOR SUGGESTED USE

Melting temperature: 890 °C

Casting temperature:

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

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

objects dimensions

Cooling casted objects: in water after 10 minutes

Cooling casted objects (with stones): 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.
