| Range 2 | 400–700 | 150–500 | 700–1500 |
| Range 3 | 700–1500 | 300–1200 | 40–600* |
Please confirm the height range for the third size group. Custom dimensions can be evaluated according to drawings and production requirements.
Titanium hollow forgings can be produced through suitable forging and forming routes, followed by machining to achieve the required dimensions and surface finish.
Depending on the product design and manufacturing process, forging or extrusion may be used to produce hollow preforms. Subsequent machining can establish the specified inner diameter, outer diameter, height, and dimensional tolerances.
The manufacturing route is selected according to the titanium grade, component dimensions, required mechanical properties, and applicable product specification.
Inspection can include the following items according to the purchase order and applicable standard:
Chemical composition analysis
Mechanical property testing
Ultrasonic testing (UT), where specified
Dimensional and surface inspection
Additional inspections or documentation as agreed with the customer
Titanium hollow forgings combine relatively low density with high specific strength and corrosion resistance in suitable service environments. They can be considered for applications where weight, corrosion resistance, and component geometry are important.
Typical application areas include:
Aerospace: Selected structural and machined components, subject to material and qualification requirements
Chemical and petrochemical processing: Corrosion-resistant equipment components
Oil and gas: Selected components for demanding operating environments
Marine and seawater desalination: Components exposed to seawater or other corrosive media
Power generation and metallurgy: Specialized equipment components
Industrial machinery: Custom hollow components manufactured to customer drawings
Titanium has a density of approximately 4.51 g/cm³ and a melting point of around 1,668°C. Its performance at elevated temperatures depends on the alloy, operating conditions, and component design.
For a quotation, please provide the material grade, outer diameter, inner diameter, height, applicable standard, heat-treatment condition, and inspection requirements.
