40Mn2 is an alloy structural steel. It refers to steel used as mechanical parts and various engineering components and containing one or several alloying elements in a certain amount. Alloy structural steel has suitable hardenability and after suitable metal heat treatment, the microstructure is uniform sorbite, bainite or extremely fine pearlite, so it has 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 manufacture machine parts with larger cross-sectional dimensions.

Application of 40Mn2
Various handling parts for the manufacture of heavy duty work such as crankshafts, axles, axles, half shafts, levers, connecting rods, joysticks, worms, piston rods, bearing bolts, screws, reinforcement rings, springs, when manufactured in diameter For parts smaller than 40mm, its static strength and fatigue properties are similar to 40Cr, so it can replace 40Cr to make important parts with small diameters
