Forged Stepped Shafts for Industrial Equipment Featuring Precision
and Durability
Our forged stepped shafts are crafted from premium alloy and carbon
steels, designed to provide exceptional precision, high mechanical strength, and long-lasting
durability. Each shaft undergoes advanced open-die forging followed by heat
treatment, ensuring uniform grain flow, dimensional accuracy, and superior wear
resistance for demanding industrial applications.
Key Features:
Precision-forged stepped design for accurate assembly fit
Heat-treated for optimal hardness and toughness
High resistance to wear, fatigue, and impact
Available in custom sizes and material grades
Suitable for subsequent machining to meet specific application
requirements
Applications:
These forged stepped shafts are widely used in heavy machinery, hydraulic systems, wind turbines, mining
equipment, and industrial drive assemblies, where reliability, precision, and long-term performance are
critical.

equipment where precision fit is critical |
| Heat Treatment Options | - Quenched + Tempered (Q+T): Maximum strength and wear resistance
for fully machined shafts <br |
The production workflow for steel forgings includes:
raw material check → unloading → verification → preheating →
forging → heat treatment → inspection → rough machining → NDT →
final quality inspection → packing → delivery.
