JIS G4053-SMn438 structural alloy steel

Key words: SMn438,JIS G4053-SMn438,SMn438 steel/plate/sheet,JIS G4053-SMn438 structural alloy steel

SMn438 Special Application
SMn438 alloy structural 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.
