Step Shaft Forging Component

Forged Step Shaft Component

Step shaft is a shaft with multiple cylinders of different diameters connected together like steps. In fact, the outer ring and plane turning constitute the turning of the stepped shaft, so it is very important to consider the dimensional accuracy and step length requirements of the outer ring when turning.

Main parameters of Step Shaft
A：≤Φ1500mm B：≤Φ900mm C：≤Φ900mm

Common technical standards of Step Shaft
A: GB/T3077 EN10083 EN10084 EN10085 JB/T6395

B: JB/T1265~1271

C: JB/T3733 JB/T4120 JB/T6393

Typical steel grades of Step Shaft
A: 18CrNiMo7-6, 17CrNiMo6, 20CrNi2Mo, 20CrMnTi, 34CrNiMo6, 30CrNiMo8, 20CrNiMo, 40CrNiMo, 35CrMo, 42CrMo

B: 35CrMo, 35CrMoV, 34CrMo1A, 20SiMn, 16Mn, 34CrNi1Mo, 34CrNi2Mo, 34CrNi3Mo

C: 9Cr2Mo, 70Cr3Mo, MC3, MC5, etc.
