Counter shaft/Intermediate shaft for boat

The intermediate shaft for boat can be strictly examined by chemical composition, tensile strength, yield strength, reduction of area, impact at low temperature, intergranular corrosion, hardness, metallographic, NDT, size, static balance etc performance parameter.

The intermediate shaft forging is one of the typical forgings frequently encountered in machines.It is mainly used to support transmission parts, transmission torque and load.Shaft forgings are rotary forgings, whose length is greater than the diameter. They are generally composed of concentric shaft outer cylinder, conical surface, inner hole and thread and corresponding end face.According to the different shape of the structure, the shaft forgings can be divided into optical shaft, step shaft, hollow shaft and crankshaft.
