Ti‑6Al‑4V (Ti‑6‑4, Grade 5) typical tensile strength depends on product form and heat treatment, but a useful rule of thumb is:
- Ultimate tensile strength (UTS): ≈ 900 MPa (≈130 ksi) in common wrought/annealed condition.
- 0.2% offset yield strength: typically ≈ 800–880 MPa (≈116–128 ksi), depending on condition.
Values vary: annealed/wrought material is around the numbers above; solution‑treated & aged or cold‑worked conditions can raise UTS up toward ~1,000–1,100 MPa (≈145–160 ksi). If you need the exact spec for a particular standard (ASTM B348, AMS, ASTM F136, etc.), product form (plate, bar, sheet, forgings) and heat treatment, tell me which and I’ll give the precise numbers.
