| Product Name | High-Density Forged Carbon Steel Blank for Gear Shaft Manufacturing |
| Material Grades | - High-strength carbon steels: 35#, 45#, customized grades available - Excellent tensile strength, impact toughness, and fatigue resistance - Designed for gear shaft cores and stepped shaft applications under torque and dynamic loading |
| Forging Equipment | - Hydraulic hammers: 5T / 8T / 12T - Large open-die forging press with optional core boring capability - Supports near-net shape forging for long shafts with solid or bored centers |
| Manufacturing Process | Hot Forging → Intermediate Heat Treatment → Optional Core Boring / Drilling → Rough / Semi-Finish Machining → UT & Dimensional Inspection |
| Forging Ratio | ≥ 3.0 — Promotes directional grain flow along shaft axis, ensuring excellent torque transmission and fatigue resistance |
| Applications | - Gear shafts, transmission shafts, coupling blanks, and stepped mechanical shafts - Widely used in gearboxes, wind turbines, heavy-duty industrial drives, and construction equipment - Withstands high torsional loads, impact forces, and cyclic stresses |
| Heat Treatment Options | - Quenched + Tempered for improved strength and wear resistance - Optional stress relief to maintain dimensional accuracy before final machining |
| Testing & Inspection | - Chemical: Spectrometer-controlled composition analysis - Mechanical: Hardness, tensile, yield, impact toughness - Ultrasonic (UT): Multi-angle flaw detection, including bore zone (if applicable) - Dimensional: Length, diameter, straightness, concentricity, and flatness |
| Value-Added Services | - Custom shaft geometries: bore size, shoulders, spline zones, flanges - Pre-machined journals, grooves, or stepped ends for gear integration - Rust-preventive coating, protective end caps, steel banding & export crate packaging - Laser part marking, OEM branding, and full traceability options |
