ASTM B265 Grade 5 Ti-6Al-4V Titanium Plate & Sheet – UNS R56400 (DIN 3.7165)
ASC LLP, Mumbai, supplies ASTM B265 Grade 5 titanium plate and sheet – Ti-6Al-4V, UNS R56400, DIN / W.Nr. 3.7165 – to ASTM B265 / ASME SB265 and, on request, AMS 4911. Material is supplied annealed, in full plates or cut to size, with EN 10204 3.1 certificates. See our titanium alloy plates and full titanium range.
What Is ASTM B265 Grade 5 (Ti-6Al-4V)?
Grade 5 is the most widely used titanium alloy. It contains about 6% aluminium and 4% vanadium, balance titanium. As an alpha-beta alloy, it has roughly 2.5 times the strength of CP Grade 2 at almost the same density (4.43 g/cm³). It can also be heat treated (solution treated and aged) for still higher strength. Grade 5 is chosen where strength-to-weight ratio, fatigue strength and toughness matter. For general corrosion service, CP Grade 2 titanium plate is usually the better and cheaper choice.

Properties of ASTM B265 Grade 5 Titanium Plates
- High strength: 895 MPa (130 ksi) minimum tensile and 828 MPa (120 ksi) minimum yield strength in the annealed condition.
- Low density: 4.43 g/cm³ – about 56% of steel – giving an excellent strength-to-weight ratio.

- Corrosion resistance: excellent in seawater and atmospheric service; less resistant than CP grades in reducing acids.
- Temperature: useful strength up to about 400 °C.
Forming, Welding & Machining Grade 5
- Forming: limited cold formability – use generous bend radii, or hot form (typically 650 – 870 °C).
- Welding: weldable by TIG, plasma and EB with full inert-gas shielding of the weld, heat-affected zone and root.
- Machining: low cutting speeds, sharp carbide tools and generous coolant; avoid work hardening and galling.

What is ASTM B265 Grade 5 titanium?
ASTM B265 Grade 5 is Ti-6Al-4V titanium alloy (UNS R56400, DIN 3.7165) in strip, sheet and plate form. It contains about 6% aluminium and 4% vanadium and is the most widely used titanium alloy.
What are the mechanical properties of Grade 5 titanium plate?
ASTM B265 requires annealed Grade 5 to have a minimum tensile strength of 895 MPa (130 ksi), minimum yield strength of 828 MPa (120 ksi) and minimum elongation of 10%.
What is the difference between Grade 5 and Grade 23 titanium?
Grade 23 is Ti-6Al-4V ELI (extra-low interstitial), with lower oxygen and iron. It has slightly lower strength (828 MPa tensile minimum) but better toughness, and is used for cryogenic and medical applications (as ASTM F136).
Is Grade 5 titanium better than Grade 2?
Grade 5 is about 2.5 times stronger than Grade 2, but Grade 2 is easier to form and weld and has better corrosion resistance in many chemicals. Grade 2 is normally used for corrosion service and Grade 5 for high-strength parts.
What is AMS 4911?
