Due to the suitable hardenability of the alloy structural steel, after the appropriate metal heat treatment, the microstructure is uniform soxite, bainite or very fine pearlite, thus having high tensile strength and yield ratio. (generally around 0.85), high toughness and fatigue strength, and low toughness-brittle transition temperature, can be used to make machine parts with large cross-sections
