DIRECTIONS FOR SUGGESTED USE
Melting temperature: 860 °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.
Cylinders temperature: from 500 °C to 600 °C depending on the machine and
objects dimensions.
