Applications of Titanium Forged Rings

Aerospace

Titanium forged rings are widely used in engine cases/segment rings, sealing and connection flanges, landing-gear and structural connection rings, and fittings in hydraulic and fuel systems at load-bearing or sealing locations.

With high specific strength, low density, and excellent fatigue performance, they maintain dimensional and property stability at intermediate temperatures (≈ ≤300–350 °C). Continuous circumferential grain flow from ring rolling improves crack resistance and service life versus discs cut from plate.

This addresses the aerospace need for "lightweight + high reliability,” increasing safety margins without adding volume while reducing fuel burn and maintenance frequency. Common grades are Ti-6Al-4V (Gr5) and Ti-6Al-4V ELI (Gr23), supplied to ASTM B381 with EN 10204 3.1 and required UT/NDT reports to facilitate finish machining to fit dimensions and surface roughness.

Medical

In medical devices and selected implant applications, titanium rings are used for external fixation frame rings, dental repair connection rings/sleeves, sealing rings for cleanroom and vacuum vessels, and mating sections of high-strength surgical instruments.

They offer biocompatibility, non-magnetic behavior, and low allergenicity; ELI grade (Gr23) provides higher purity and toughness. Controlled surface roughness and cleanliness aid assembly and sterilization, addressing the challenge of long-term stability and safety in contact with the human body or medical media by reducing rejection and imaging interference, lowering instrument failure risk, and extending service life.

Common choices are Gr23/Gr5 or industrial CP Gr2, forged to ASTM B381 and alignable with ISO/ASTM medical material requirements, with options for bright machining, pickling/passivation, or identification anodizing.

Chemical Engineering and Petrochemicals

In strongly corrosive chloride- and sulfide-bearing media, titanium rings serve as transition rings for heat-exchanger tube sheets, corrosion-resistant flange rings, column/vessel connectors, mating rings in pump and valve bodies, and other critical seals.

CP and alloyed titanium resist pitting, crevice corrosion, and stress-corrosion cracking; in activated/reducing media, Gr7 (Ti-0.2Pd) and Gr12 (Ti-0.3Mo-0.8Ni) perform especially well.

They solve the rapid-failure problem of conventional stainless steels in chlorides and seawater by greatly extending overhaul intervals, reducing leakage and downtime losses, and lowering life-cycle costs. Forgings and UT evidence can be provided to ASTM B381, and H₂S service can be coordinated to NACE MR0175/ISO 15156.

Electrolysis (Chlor-alkali, Nonferrous, Green Hydrogen)

Electrolytic industries use titanium rings for bus/compression rings, anode/cathode chamber connection flange rings, diaphragm-cell sealing rings, and mating bases for coated anodes/cathodes.

Titanium is highly inert and dimensionally stable in chloride electrolytes and compatible with MMO/iridium-based coating systems; controlled flatness and roughness reduce contact resistance and improve current efficiency.

This addresses issues under long-term energization and strong corrosion—fixture loosening, seal degradation, and polarization efficiency loss—thereby extending cell life and stabilizing output. Gr1/Gr2 are commonly used substrates, with Gr7 selected for harsher corrosion; supply follows ASTM B381, with optional surface pretreatment and long-duration immersion/polarization qualification to project specs.

Electroplating

In nickel/chrome/PCB plating lines, titanium rings are commonly applied as plating-tank sealing rings, anode-basket end rings, fixture/jig support rings, sight-glass/manhole cover rings, and corrosion-resistant mating components.

Titanium is inert to most plating chemistries and does not leach contaminants, maintaining dimensions and strength during prolonged immersion; reliable sealing is easily achieved with liners such as PTFE/PP/PVDF. This mitigates scrap, line stoppages, and coating non-uniformity caused by corrosion and contamination, stabilizing yield and lowering operating costs.

Gr2 is commonly used, with Gr7/Gr12 for severe or crevice-sensitive conditions; forgings are supplied to ASTM B381 with surfaces and tolerances finished to fixture standards.

Nuclear Power Equipment

Applications include condenser and seawater-cooling flanges on the seawater side and in ambient-temperature auxiliary systems, corrosion-resistant mating rings in chemical volume-control and water-treatment units, and seal interfaces in pumps and valves.

Thanks to excellent corrosion resistance in seawater and chloride environments, non-magnetic and low-contamination characteristics, long-term dimensional stability, and the support-load reduction from lightweighting, titanium rings help suppress efficiency loss and unplanned outages caused by corrosion and scaling.

They increase availability and O&M safety while reducing long-term replacement and maintenance costs.

Processing Methods for Titanium Forged Rings

Manufacturing Process

The typical route heats the billet, performs repeated upsetting and edging, then punches a center hole in the preform with a die. The hole is expanded with tooling to near-net size, followed by rough and finish machining as required. Semi-finished rings are then inspected, packaged, and shipped.

Surface Finishing

As-forged finish is economical and durable and is suitable for subsequent rough machining or heat treatment.

Machined bright finish can reach surface roughness Ra ≤ 0.8 µm, ideal for clean or assembly environments such as medical and vacuum applications.

Passivation forms a dense oxide film to enhance corrosion resistance and is recommended for marine and chemical service.

Anodic coloring in black, blue, and other tones can be used for identification or appearance, selected according to service conditions and standards.

Packaging

Waterproof film with shock-absorbing foam on wooden pallets is used as the standard package, and large rings are additionally braced with steel frames to prevent deformation in transit.

Medical-grade rings are sealed in sterile vacuum packaging to avoid contamination.

Export-standard, seaworthy moisture-proof packaging can be customized to customer requirements.

Inspection and Testing

Chemical composition is verified by spectrometric analysis to confirm alloy conformity.

Mechanical properties are tested for tensile, impact, and hardness to validate strength and toughness.

Nondestructive testing includes UT ultrasonic testing and RT radiographic testing to detect internal defects.

Dimensional accuracy is checked with CMM measurement to ensure tolerance compliance, and third-party reports such as SGS or BV can be provided.
