Chalco Titanium titanium forged shaft types
Chalco Titanium can provide different types of titanium forged shaft, covering conventional straight shafts, complex stepped shafts and variable-section shafts for different equipment and project requirements.
Straight shaft
Formed by open-die drawing, with constant-section shaft blanks available in different diameters and lengths. Machining allowance can be reserved for subsequent turning.
Stepped shaft
Can be forged into continuous shaft sections with multiple diameters, bringing the blank profile closer to the final part and reducing material removal compared with turning the entire part from a large-diameter bar. TC4, TA15 and other titanium alloy stepped shafts are available.
Tapered shaft
Radial precision forging can form a continuously varying tapered section, with shaft diameters and the taper profile at different positions controlled according to the drawing.
Variable-diameter shaft
Suitable for complex shafts with multiple diameter changes. Section-by-section forming can be performed by radial precision forging, with TC11 and other titanium alloy variable-diameter shaft blanks available.
Agitator shaft
Long titanium alloy agitator shafts can be supplied as one-piece forgings for chemical mixing and corrosion-service equipment, with TA2 / Grade 2 and other materials available.
If your project involves complex steps, diameter transitions or special-shaped shaft structures, Chalco Titanium can provide a targeted titanium forged shaft forming solution based on your drawing.

Titanium forged shaft alloy selection guidance
If corrosion performance is the main concern, TA2 can be considered first. For shaft components requiring a balance of strength, weight and general versatility, TC4 is a commonly used option. TA15 can be considered for aerospace and high-performance structural shafts, while TC6 can be selected for high-load shaft components. For high-performance variable-diameter shafts and complex shaft blanks, TC11 can be considered.
If you are unsure which titanium alloy is more suitable for your project, provide the service environment, load conditions and drawing requirements. Chalco Titanium can assist in recommending an appropriate titanium forged shaft grade.

Chalco Titanium titanium forged shaft machining and dimensional control
For long, stepped and variable-section titanium forged shafts, Chalco Titanium can control the forged blank based on the final part dimensions and subsequent machining plan to reduce downstream machining difficulty.
Titanium forged shaft vs. machined titanium bar
For large-diameter stepped, tapered and variable-section shafts, turning directly from a constant-diameter titanium bar often requires substantial material removal. A titanium forged shaft can be shaped during forging so that the blank profile is closer to the final part geometry.
| Comparison item | Titanium forged shaft | Machined titanium bar |
| Blank shape | Steps, tapers and diameter transitions can be pre-forged | Usually starts from a constant-diameter round bar |
| Material utilization | Less material removal for complex shaft geometries | More machining for shafts with large diameter differences |
| Machining allowance | Can be reserved for each shaft section according to the final drawing | Determined by the original bar size |
| Subsequent machining | Reduces rough turning and heavy material-removal operations | Usually requires more rough machining |
| Suitable products | Large, stepped, tapered and complex shaft components | Simple, small-size shaft components |
Chalco Titanium titanium forged shaft manufacturing process
Chalco Titanium develops the forging process according to the titanium alloy grade, shaft-section structure and final dimensions. Open-die forging and radial precision forging are combined to form straight, stepped, tapered and other complex shaft forgings.
Raw material inspection → Saw cutting → Heating → Open-die breakdown forging → Radial precision forging → Heat treatment → Straightening → Machining → Inspection
Raw material inspection and cutting
Verify the material grade, heat number and raw material quality, then saw-cut the stock according to the forged-shaft diameter, length and shaft-section structure, reserving an appropriate billet size for subsequent upsetting, drawing and precision forging.
Heating
Heating schedules are established for different titanium and titanium alloy grades. The heating furnaces can reach up to 1250°C, with TUS controlled to ±7°C for gas-fired furnaces and up to ±5°C for electric furnaces, supporting more consistent heating of long and large-section billets.
Open-die breakdown forging
A rapid forging press is used for upsetting, drawing and related operations to adjust billet cross-section and length and provide sufficient plastic deformation. Large forgings can be broken down on a 100MN rapid forging press, with forging control accuracy up to ±1 mm.
Radial precision forging
Stepped, tapered and special-shaped shafts can be formed on an RF-40 horizontal CNC radial precision forging machine:
- Maximum feed size: 500 mm
- Maximum forging force: 950 t
- Maximum forging frequency: 290 strokes/min
- Standard forged diameter for solid round parts: Φ60–400 mm
- Special diameter: up to Φ450 mm
- Maximum bar processing length: 13,000 mm
- CNC radial precision forging controls the diameter and profile of different shaft sections, bringing the blank closer to the final part shape.
Heat treatment and straightening
The heat-treatment schedule is established according to the alloy grade, property requirements and delivery condition. Long shafts can be straightened after heat treatment to improve forging straightness and provide a stable machining reference for subsequent turning and finish machining.
Rough and finish machining
Products can be supplied as-forged, rough-machined or with further machining according to delivery requirements. Turning equipment can handle workpieces up to Φ1250 × 5000 mm, allowing machining of outside diameters, steps and different shaft sections, with machining allowance retained or removed according to the final drawing.
Inspection and delivery
Dimensional, chemical composition, mechanical property and internal-quality inspections are completed, with UT, PT and other nondestructive testing available according to order requirements. After confirming the product against the drawing and purchasing technical requirements, it is marked and packed.
