Definition of low alloy steel
WebMelting point of 41xx steel – chromoly steel is around 1427°C. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid can exist in equilibrium.
