Titanium rolled products: types, grades and applications
Titanium rolled products are a broad range of semi-finished products and finished items obtained by plastic deformation (rolling, extrusion, forging, drawing) from titanium and its alloys. Titanium rolled products are a key structural material for the aerospace, chemical, oil and gas, medical, energy and shipbuilding industries. Due to the unique combination of high specific strength, exceptional corrosion resistance, biocompatibility and a wide range of operating temperatures, titanium and its alloys have no alternatives in many critical applications. On an industrial scale, titanium rolled products are produced in the form of sheets, plates, rods, pipes, profiles, wire, forgings and stamped blanks.
Classification and Range of Titanium Rolled Products
The range of titanium rolled products includes several main groups differing in geometry, production technology and application.
Sheets and plates. This is flat rolled products manufactured by hot or cold rolling. Titanium sheets typically have a thickness of 0.3 to 10 mm, plates — from 10 to 100 mm and more. Sheet products are one of the most in-demand types of products: they account for about 75% of all titanium rolled products for industrial applications. Sheets and plates are produced according to GOST 22178-76, which establishes technical requirements for products from titanium and titanium alloys.
Rods. Round, square and hexagonal rods are produced by hot rolling or extrusion. They are used for subsequent machining, forging and the manufacture of fasteners. Round rods are produced according to GOST 26492-85.
Pipes. Titanium pipes are divided into seamless hot-deformed and cold-deformed, as well as welded. They are produced according to GOST 24890-81 and are widely used in heat exchangers, chemical equipment and pipelines.
Profiles. Shaped titanium profiles have a smooth surface and uniform cross-section, and are produced in standard and non-standard configurations.
Wire. Titanium wire is used for welding materials, electrodes and special products.
Forgings and stamped blanks. Large-sized products obtained by forging and stamping are used for critical parts of aircraft engines and power engineering.
Grades of Titanium and Titanium Alloys
The grades of titanium and wrought titanium alloys intended for the manufacture of semi-finished products are established by GOST 19807-91. All alloys are divided into several groups by structure and ability to be strengthened by heat treatment.
Technical titanium (α-alloys, non-heat-treatable). This group includes grades VT1-00, VT1-0, VT1-1. They possess maximum ductility and corrosion resistance, but relatively low strength. The titanium content in VT1-0 is 99.2–99.7%. These grades are used for chemical equipment, medical implants and products where corrosion resistance is important rather than high strength.
Pseudo-α-alloys. These include OT4-0, OT4-1, OT4, VT20. They can be strengthened by heat treatment with the formation of titanium martensite, but the degree of strengthening is small. Alloy VT20 is characterised by increased heat resistance and is used in aircraft construction.
Two-phase (α+β) alloys. This is the most numerous and in-demand group, strengthened by quenching and aging. Typical representatives are VT6, VT3-1, VT8, VT9, VT14. Alloy VT6 (Ti-6Al-4V) is a universal high-strength alloy with an optimal combination of technological and mechanical properties: tensile strength is 1100–1250 MPa. Alloys VT3-1 and VT8 are characterised by heat resistance up to 450–500 °C. These alloys are widely used in the aerospace industry for engine parts and airframe elements.
β-alloys and pseudo-β-alloys. These include VT15, VT22, VT32. They possess high ductility in the quenched state and high strength after aging. They are used for highly loaded parts and fasteners.
Production Technology
The production of titanium rolled products includes several successive stages. The starting material is titanium sponge, which, together with alloying elements, is pressed into electrode blocks and remelted in vacuum arc or electron beam furnaces to produce ingots.
The resulting ingots are subjected to hot pressure treatment: forging, extrusion and rolling. Titanium alloys are processed by open-die forging on the same equipment as steel, but at a lower deformation rate. Optimal forging temperatures are typically in the range of 790 to 1065 °C. Rolling of titanium and its alloys is used to manufacture sheets, shaped profiles and pipes.
To obtain sheets and plates, ingots or slabs are heated and rolled on hot rolling mills, and then, if necessary, subjected to cold rolling with intermediate anneals. Rods are obtained by hot rolling or extrusion, pipes — by hot piercing followed by cold rolling or drawing. The final stages of production are heat treatment (annealing, quenching, aging), pickling, straightening and quality control.
Applications
Aerospace industry. This is the key and most demanding consumer of titanium rolled products from high-strength alloys VT6, VT3-1, VT8, VT20. Titanium is used to manufacture aircraft engine parts, airframe elements, skin, load-bearing structure and landing gear parts. The high specific strength of titanium allows the weight of structures to be reduced and their reliability to be increased.
Chemical and petrochemical industry. Titanium rolled products (sheets, plates, pipes) are used for the manufacture of reactors, heat exchangers, pipelines, pumps and valves operating in aggressive environments. About 60% of industrial titanium consumption comes from the chemical industry, including equipment for terephthalic acid production.
Medicine. Due to their biocompatibility, titanium is used for the production of implants (joint endoprostheses, bone plates, screws), surgical instruments and dental structures.
Energy. Titanium pipes and sheets are used in heat exchangers of power plants, desalination plants, cooling systems and nuclear reactors. The energy sector accounts for about 10% of global industrial titanium consumption.
Shipbuilding. Titanium rolled products are used for ship hulls, decks, superstructures and marine technology due to their high corrosion resistance in seawater. Global shipbuilding consumption of titanium is estimated at 9%.
HVAC and desalination. A growing segment associated with the replacement of freon with ammonia in heating, ventilation and air conditioning systems, as well as with water desalination.
Other applications. Titanium rolled products are used in the automotive industry, oil and gas extraction, sports equipment and consumer goods.
Safety and Storage
Titanium rolled products in massive form do not present a chemical hazard. However, titanium dust and fine chips generated during machining are pyrophoric and can be fire- and explosion-hazardous. When working with titanium, personal protective equipment (respirators, safety goggles, gloves) must be used and effective ventilation of premises must be ensured. Titanium rolled products should be stored in dry, well-ventilated areas, protected from moisture and contamination. Long-term storage of titanium sponge and finely dispersed waste requires special precautions due to possible self-heating.
Market and Trends
The global market for titanium rolled products demonstrates steady growth. China is the undisputed leader in the production of titanium rolled products for industrial applications, followed by Japan, the USA and Russia. In 2024, China produced 64% of the world's titanium rolled products and consumed 56%. Russia maintains its position in the production of high-quality titanium rolled products for the aerospace industry, but sanctions restrictions and reorientation to the domestic market have led to a decrease in effective output.
Key industry trends include growing demand for titanium from civil aircraft construction, the chemical industry and energy, the development of technologies for producing high-strength and heat-resistant alloys, and tightening requirements for product quality and traceability. Producers with a full cycle — from sponge to finished rolled products — occupy stable competitive positions.
Conclusion
Titanium rolled products remain a fundamental material of modern industry, providing the production of critical structures and equipment for the aerospace, chemical, medical, energy and shipbuilding industries. Understanding the classification, grade composition, production technologies and applications of titanium rolled products is the basis for competent material selection and the organisation of efficient supplies.
