Description of the casting and technological parameters

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
