Key Features & Benefits
Better Mechanical Sturdiness
Internal porosity that is typical of castings is eliminated via forging. In cyclic loading situations, aligned grain flow results in a 40% increase in fatigue resistance.
Outstanding Resistance to Corrosion
A stable oxide layer is formed by titanium of grade 2. This keeps your equipment safe against deterioration in harsh chemical conditions and seawater that is high in chloride.
Strong but Lightweight
Our rings have outstanding strength-to-weight ratios and weigh 40–50% less than steel equivalents. At the same time, you lower transportation expenses and structural burdens

Manufacturing Process
Selection of Raw Materials
We source ASTM-compliant high-purity titanium sponge. Before melting, composition is verified by chemical analysis.
Forming and Forging
At 850–950°C, hydraulic presses apply regulated compression. Defects are removed and grain structure is refined. Ring rolling increases diameters while preserving consistency in wall thickness.
Heat Therapy
Remaining tensions are released by annealing at regulated temperatures. When necessary, solution treatment and aging maximize mechanical qualities for high-stress applications.
Machining & Finishing
CNC machines achieve tight tolerances. Surface treatments like pickling remove alpha case, ensuring corrosion resistance meets specification requirements.
Quality Inspection
Chemical Testing
Optical Emission Spectrometry validates alloy composition. Inert Gas Fusion measures oxygen, nitrogen, and hydrogen levels precisely.
Ultrasonic Testing (UT)
100% volumetric inspection per ASTM E1444 detects internal discontinuities. You receive zero-defect forgings free from laps or inclusions.
Mechanical Testing
Tensile tests confirm yield strength, ultimate tensile strength, and elongation meet Grade F-2 requirements (≥345 MPa yield, ≥483 MPa tensile).
Dimensional Verification
CMM equipment checks outer diameter, inner diameter, and wall thickness. Tolerances stay within ±0.5mm unless tighter specifications are requested.
Applications
Chemical Processing Plants
Our Titanium Forged Ring Forging serves as sealing rings in reactors handling nitric acid and chlorine gas. The forged structure prevents leak paths in pressure vessels.
Marine Engineering
You'll find these rings in seawater desalination pumps and offshore platform risers. Galvanic corrosion resistance ensures 20+ year service life in harsh saltwater.
Power Generation
Heat exchangers and condenser systems use our rings for flange connections. Thermal stability maintains integrity during temperature cycling operations.
Aerospace Components
Lightweight rings function as structural retention elements in jet engine casings where high-temperature strength is critical up to 400°C.

FAQ
Q: What distinguishes cast titanium rings from forged ones?
A: Directional grain flow with increased impact toughness is produced by forging. Castings may have porosity problems and a haphazard grain structure.
Q: Is heat treatment necessary for Grade F-2?
A: In order to reduce forging stresses and maintain dimensions, our Titanium Forged Ring Forging is indeed annealed.
Q: What production size restrictions are in place?
A: For big industrial vessel applications, our forging press can handle rings with an outer diameter of 100 mm to more than 3000 mm.
Q: Are material test reports available?
A: EN 10204 3.1 MTR with the heat number, chemical composition, and mechanical test findings is included with every shipment.
Q: How much is the minimum order quantity?
A: Orders for stock begin at 100 kg. For new clients, trial orders are supported with a flexible MOQ.
