RE: Minimum temperature range for common low carbon steels. The ductile to brittle transition temperature can vary considerably for low carbon steels, and is dependent on grain size, heat treatment and alloy content. The fracture appearance transition temperature for 50% flat fracture (FATT @ 50%) is a good reference point for comparing materials.
