Parameter | Units of measurement | Description |
---|---|---|
melting point | °C | The temperature at which solid crystalline body makes the transition to the liquid state and Vice versa |
Hot working temperature | °C | The temperature at which the plastic-deformed metal recrystallizes during the pressure treatment |
annealing temperature | °C | The temperature at which the processes return recrystallization and homogenization of the metal to reduce its hardness for subsequent machining |
