Alloy structural steel refers to steel used as mechanical parts and various engineering components and containing one or several certain amount of alloying elements. Alloy structural steel has suitable hardenability, after suitable metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite, so it has a high tensile strength and yield ratio. (Generally around 0.85), higher toughness and fatigue strength, and lower toughness-brittle transition temperature, can be used to manufacture machine parts with larger cross-sectional dimensions. It can be divided into ordinary alloy structural steel and special-purpose alloy structural steel. The former includes low-alloy high-strength steel, low-temperature steel, ultra-high-strength steel, carburized steel, quenched and tempered steel and non-quenched and tempered steel; the latter includes spring steel, ball bearing steel, free-cutting steel, cold stamping steel, etc.
