Product Description for Titanium Grade 5 Round Bar
Titanium Grade 5 Round Bar is a solid cylindrical bar produced from titanium alloy Ti-6Al-4V, UNS R56400. Bar and billet are supplied to ASTM B348 / B348M, with forgings covered by ASTM B381 and aerospace material typically ordered to AMS 4928. The material number is 3.7165. Grade 5 accounts for more than half of all titanium used worldwide.
The alloy contains 5.50-6.75% aluminium and 3.50-4.50% vanadium. Aluminium stabilises the alpha phase and vanadium stabilises beta, producing a two-phase alpha-beta structure that can be strengthened by heat treatment. In the annealed condition minimum tensile strength is 895 MPa with 828 MPa minimum yield and 10% minimum elongation. Solution treating and ageing raises strength further, typically above 1100 MPa in suitable sections.
At 4.43 g/cm3 it is roughly as strong as quenched and tempered alloy steel at 56% of the density. Corrosion resistance is good in seawater and chlorides, though slightly below the commercially pure grades in strongly oxidising acids. Useful strength is retained to about 400 deg C.
Bar is supplied annealed or solution treated and aged in diameters from about 6 mm to 350 mm and lengths of 3 to 6 m. An extra-low interstitial variant, Grade 23 or Ti-6Al-4V ELI, is used where fracture toughness and cryogenic performance are critical.
Typical applications include aerospace structural components, engine parts, fasteners, landing gear fittings, orthopaedic implants, marine and offshore hardware, motorsport components, downhole tools and high-performance sports equipment.
Common Applications of Titanium Grade 5 Round Bar
➡️ Machined shafts, spindles, valve stems, pump sleeves and pins for food, beverage, dairy and pharmaceutical equipment, where the passive chromium oxide film resists both product acids and caustic clean-in-place chemicals.
➡️ Fasteners, studs, bolts, threaded rod and anchor components produced from bar stock, chosen for corrosion resistance combined with the ductility needed for cold heading and thread rolling.
➡️ Chemical, water treatment and general process plant parts such as agitator shafts, flange blanks, nozzles and support components handling water, steam and mildly corrosive media free of significant chlorides.
➡️ Architectural and structural hardware including handrail stanchions, balustrade fittings, tension rods and bollards, where a bright ground or polished bar finish provides both appearance and low maintenance.

Technical Specifications

Titanium Grade 5 Round Bar is supplied to ASTM B348 / B348M, adopted by ASME as SB348 for pressure applications, with forgings under ASTM B381 as Grade F-5. Aerospace material is normally ordered to AMS 4928, which adds requirements for melting practice, macrostructure, microstructure and ultrasonic inspection. Surgical implant material follows ISO 5832-3 or ASTM F136.
Unlike the commercially pure grades, Ti-6Al-4V is an alpha-beta alloy and can be strengthened by heat treatment. Mill annealing at 700-790 deg C followed by air cooling is the standard supply condition and gives the values quoted in ASTM B348. Solution treatment at 900-955 deg C followed by a water quench and ageing at 480-595 deg C raises strength well above the annealed level, though hardenability limits the useful depth to sections of roughly 25-40 mm.
The beta transus is approximately 995 deg C. Working or heat treating above this temperature transforms the structure entirely to beta and, on cooling, produces a coarse lamellar structure with higher fracture toughness and creep strength but lower ductility and fatigue strength.
Machining is difficult. Thermal conductivity is only 6.7 W/m.K, so heat concentrates at the cutting edge. Rigid setups, sharp tooling, low speeds, heavy positive feeds and flood coolant are essential.
Welding by GTAW, plasma or electron beam requires full inert gas shielding, and post-weld stress relief is normally applied.

Chemical Composition
View the chemical composition and applicable material limits for Ti Gr 5 Round Bar
Aluminium at 5.50-6.75% is an alpha stabiliser. It dissolves in the hexagonal alpha phase and strengthens it by solid solution, raises the beta transus temperature and reduces density. The 6% level is close to the practical maximum, since higher aluminium promotes formation of the brittle ordered Ti3Al alpha-2 phase during prolonged exposure at elevated temperature.
Vanadium at 3.50-4.50% is a beta stabiliser. It lowers the beta transus and retains a proportion of body-centred cubic beta phase at room temperature, typically 5-10% in the annealed condition. The presence of two phases is what makes the alloy heat treatable, since solution treatment and ageing controls the amount, size and distribution of the transformed beta.
Oxygen at 0.20% maximum is an interstitial strengthener, held lower than in Grade 4 because the aluminium and vanadium already supply the required strength and excess oxygen would reduce fracture toughness. In the extra-low interstitial variant, Grade 23, oxygen is capped at 0.13% specifically to improve toughness and cryogenic performance.
The 0.40% maximum on iron is there despite iron being a beta stabiliser, because it segregates during solidification and can form beta-flecks, local regions of odd composition that hurt fatigue performance.
The 0.015% ceiling on hydrogen is there because titanium hydride platelets cause delayed brittle failure. Nitrogen and carbon are limited as embrittling residuals, and other residuals are held to 0.10% each and 0.40% in total.

The values listed for the annealed condition are the requirements of ASTM B348 / B348M for Titanium Grade 5 bar: minimum tensile strength 895 MPa, minimum 0.2% offset yield strength 828 MPa and minimum elongation 10% in 50 mm. Reduction of area of 25% is also a mandatory minimum. Testing follows ASTM E8 / E8M, and B348 sets no hardness requirement for this grade.
Unlike the commercially pure grades, Ti-6Al-4V responds to heat treatment. Solution treating at 900-955 deg C with a water quench, followed by ageing at 480-595 deg C, typically produces tensile strengths around 1100 MPa with yield near 1000 MPa. The effect is limited by hardenability, however, and in sections much above 25-40 mm the interior does not fully respond, so most heavy bar is supplied mill annealed.
Two microstructural cautions apply. Working or heat treating above the beta transus of approximately 995 deg C produces a coarse lamellar structure with better fracture toughness and creep resistance but reduced ductility and fatigue strength. Prolonged exposure above roughly 400 deg C can precipitate the brittle Ti3Al alpha-2 phase.
Where fracture toughness or cryogenic performance governs, Grade 23 (Ti-6Al-4V ELI) with oxygen limited to 0.13% should be specified instead.
