DIRECTIONS FOR SUGGESTED USE

Melting range (Solidus – Liquidus): 857 - 908 °C

Casting temperature:

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

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

140 °C over its Liquidus 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.)
