SMn438 alloy steel strength,plasticity,high wear resistance,but the cold deformation plasticity is not high and poor weldability.SMn438 used to working under heavy load of conditioning parts,such as axle,axle shaft,crankshaft,axle,screw,worm,piston rod,joysticks,levers,connecting rod,a load of bolts,screws,reinforcing ring,spring,etc;.
SMn438 alloy structural steel under 40 mm in diameter is used as the important parts with small section,and was equal to that of 40 cr steel.
Delivery status of SMn438 structural alloy steel:hot rolling,controlled rolling or normalizing/AR,CR/N.
