VT22I
VT22I Titanium Alloy for Heavy-Load Aerospace and Industrial Components
VT22I Titanium (ВТ22И) is a high-strength, heat-treatable α+β titanium alloy used for heavily loaded parts where toughness, fatigue resistance, and long-term reliability are required. VT22I is supplied in wrought forms such as plate, bar, forgings, and stampings, and is typically selected for aerospace and heavy engineering applications that operate under high stress and demanding service conditions.
VT22I belongs to the VT22 family of high-alloyed titanium grades and is associated with high strength levels that depend on the supplied condition and heat treatment. In practice, the alloy is used when designers need a strong combination of strength, ductility, and section hardenability for large, load-bearing components.
What is VT22I Titanium Alloy?
Composition and Microstructure
VT22I is an α+β titanium alloy that uses β-stabilizing elements to achieve high strength after solution treatment and aging. When processed correctly, VT22I can be tuned to microstructures that balance strength with usable ductility for heavy-duty aerospace and industrial parts.
The best performance is typically achieved by controlled deformation and heat treatment that forms a stable (α + β) structure. Depending on the route (forging/rolling + solution treatment + aging), the alloy can be optimized toward higher strength or improved plasticity for large stampings and load-bearing parts.

Key Features of VT22I Titanium Alloy
High Strength
VT22I is selected for heavy-load parts where high tensile strength and strong load-bearing capacity are required after proper heat treatment.
Fatigue Resistance
The alloy supports good fatigue performance under cyclic stress, making it suitable for aerospace structures and rotating assemblies.
Corrosion Resistance
Like many titanium alloys, VT22I provides good resistance to corrosion, helping extend service life in harsh environments.
Heat-Treatable Performance
VT22I is heat treatable and can be processed to achieve a targeted balance of strength and ductility depending on the application.
Large-Section Hardenability
One practical advantage of VT22-family alloys is the ability to retain high strength through thicker sections when processed correctly.
Low Density
Titanium’s low density supports weight reduction, which is critical for aerospace structures and high-performance engineering components.
