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.

| Product Name | Forged Stepped Shafts for Industrial Equipment Featuring Precision and Durability |
| Material Grade | - Premium alloy steels: 42CrMo, 42CrMo4, 18CrNiMo7-6 - Optimized for mechanical strength, toughness, and wear resistance, specifically for stepped shaft geometries and industrial assemblies |
| Forging Equipment | - Hydraulic Open Die Hammers: 5T, 8T, 12T - Engineered for forging medium-to-large stepped shafts with consistent directional grain flow to enhance fatigue performance and precision |
| Manufacturing Process | Raw Material Inspection → Open Die Forging → Heat Treatment (Normalizing or Quenching + Tempering) → Rough or Precision Machining → Ultrasonic Testing (UT) → Dimensional Verification |
| Forging Ratio | ≥ 3.0 — Ensures uniform fiber alignment, optimal stress distribution, and high durability under cyclic and heavy-duty operational loads |
| Applications | - Stepped shafts for industrial drives, hydraulic systems, and heavy machinery - Transmission shafts and spindles with stepped features - Shafts used in mining, construction, and port handling 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.
