Rundong crankshaft is made of 4340 alloy steel with high content of nickel through forging process, significantly preventing the generation and propagation of cracks. Thanks to abundance of nickel, the crankshaft also features high corrosion resistance. Furthermore, static balance will be achieved when the crankshaft works, ensuring smooth operation and reducing noise and vibration. As a result, the working life is greatly extended.
