High Light custom carbon steel blanksteel forging blank customhigh density steel forging blank
High-Density Forged Carbon Steel Blank for Gear Shaft Manufacturing. Our High-Density Forged Carbon Steel Blanks are precision-engineered for the manufacture of gear shafts used in high-load and high-torque applications. Produced through controlled hot forging and optimized grain flow orientation, these blanks deliver outstanding mechanical properties and dimensional consistency essential for gear machining and shaft integration.

Key Features:

  • Material Options: High-quality carbon steel grades such as 35#, 45#, or customized compositions

  • Dense Internal Structure: Enhanced through ≥3.0 forging ratio to eliminate porosity and internal defects

  • Optimized Grain Flow: Aligned along shaft axis for superior torque transmission and fatigue strength

  • Excellent Machinability: Suitable for gear hobbing, milling, and turning operations

Applications:

  • Gear shafts, transmission shafts, spline shafts, and stepped shafts

  • Widely used in gearboxes, reduction units, wind turbines, mining machinery, and heavy-duty industrial drives

  • Engineered to handle rotational stress, shock loading, and long service cycles

 

Item Details
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

 

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
