Overview


Alloy structural steel is so called because this kind of steel contains certain other alloy elements, and it is applied for fabrication of machine parts and construction components. Alloy structural steel has proper hardenability. The microstructure becomes fine pearlitic, sorbite, bainite structure after proper steel heat treatment, thus having high tensile strength and yield ratio (average value 0.85), high toughness and fatigue strength, with lower ductile brittle transition temperature, which makes is suitable for making machine parts with large sectional diamension.    

Alloy structural steel can be generally divided into quenched and tempered alloy structural steel and surface hardened alloy structural steel. The former is suitable for making shafts and connecting rods bearing large load; the latter is suitable for making components with hard and wear-resisting surface and soft heart, such as gears and shafts.
