Titanium sheet, strip & plate · ASTM B265 · all grades

ASTM B265 is the base specification for titanium and titanium-alloy strip, sheet and plate. SXQYTD stocks the grades buyers actually order — Gr1–Gr4, Gr5, Gr7, Gr9, Gr11, Gr12 and Gr23 — and cuts to size with mill test certificate and PMI. Below is the procurement detail that decides grade, form and thickness before you issue a PO.

Material	Gr1–4, Gr5, Gr7, Gr9, Gr11, Gr12, Gr23	Principle	Self-healing TiO₂ film, chloride-proof
Form & stock	Strip / sheet / plate, 0.3–100 mm	Industry	Chemical, aerospace, medical, marine
Standard	ASTM B265 / ASME SB-265	Lead time	1–3 days stock; 3–7 days cut

1. What ASTM B265 covers — by form and by grade

By form, B265 covers three flat products: strip (narrow-width coiled flat), sheet (flat, at or below 4.76 mm / 3/16 in) and plate (flat, at or above 4.76 mm). Same alloy, different thickness, tolerance and rolling route. By grade, the spec lists the full family — the four commercial-purity grades Gr1–Gr4, the palladium grades Gr7 and Gr11, the Mo/Ni grade Gr12, the alloy grades Gr5 (Ti-6Al-4V) and Gr9 (Ti-3Al-2.5V), and the ELI grade Gr23 (Ti-6Al-4V ELI). Each grade has its own chemistry and mechanicals in the same table.

2. Grade selection — grade vs. property vs. use

Pick the grade by what the part must do, not by habit:

Grade	Key property	Typical use
Gr1	Highest ductility	Deep-formed, thin parts.
Gr2	Best balance	General corrosion service.
Gr3 / Gr4	Higher CP strength	Light structural.
Gr5 / Gr23	High strength (ELI for med/aero)	Aerospace, medical implants.
Gr7 / Gr11	Pd — reducing-acid resistance	Reducing acid duty.
Gr9	Strength + formability	Tubes, sports, structural.
Gr12	Mo/Ni — low-cost acid grade	Reducing acid, cheaper than Gr7.

Three limits to keep in mind: (1) above ~315°C titanium absorbs oxygen and embrittles, so B265 grades are low/medium-temperature materials; (2) titanium has poor anti-galling behaviour, so bolted joints and sliding fits need lubrication or separation; and (3) fatigue is notch-sensitive — avoid sharp corners. We flag these on the drawing review rather than after delivery.

3. Technical standards we supply to

• Base spec: ASTM B265 / ASME SB-265, MTC EN 10204 3.1 with chemistry and mechanicals.
• Cross specs: AMS 4900 / 4911 (aerospace), GB/T 3621 (China), DIN 17860, ISO 5832-2 (medical).
• Chemistry & mechanicals: per the grade table in B265 — e.g. Gr2 tensile ≥ 345 MPa, yield ≥ 275 MPa, elongation ≥ 20 %.
• Tolerance & surface: thickness tolerance per B265; surface descaled, free of α-case; PMI verified.

4. Manufacturing flow — from melt to your size

1) Titanium sponge + alloy → triple VAR melting → 2) Forging to slab → 3) Hot rolling (plate / thick sheet) → 4) Cold rolling to gauge (sheet / strip) → 5) Vacuum annealing → 6) Pickling / descaling → 7) Leveling and straightening → 8) Shearing / slitting to size → 9) PMI and inspection → 10) Export packing. The cold-rolled route gives sheet and strip their tight tolerance and clean surface.

5. Key performance

Item	Representative value	Note
Density	4.51 g/cm³	~60 % of steel weight.
Tensile (Gr2 / Gr5 / Gr12)	≥ 345 / 895 / 483 MPa	Per B265 grade.
Yield (Gr2 / Gr5 / Gr12)	≥ 275 / 828 / 345 MPa	Alloy grades far stronger.
Thickness tolerance	Per B265 (tight for cold-rolled)	Sheet/strip tighter than plate.
Surface	Pickled / descaled, no α-case	PT-grade on request.

6. Application industries

Industry	Grade	Use
Chemical / process	Gr2 / Gr7 / Gr12	Linings, trays, tube sheets.
Aerospace	Gr5 / Gr23	Structural, airframe parts.
Medical / device	Gr23 / Gr2	Implants, instruments.
Marine / desalination	Gr2	Seawater service.
Heat exchanger	Gr2	Tube sheets, baffles.

7. Selection guide

By property: maximum formability → Gr1; balance → Gr2; higher strength → Gr3/Gr4; high strength → Gr5/Gr23; reducing acid → Gr7/Gr12 (Gr12 cheaper); tube/structural → Gr9. By form: strip for stamped/formed parts, sheet for general fabrication, plate for structural blocks — the 4.76 mm line in B265 decides sheet vs plate. Send medium, temperature, thickness and quantity; we confirm grade and cut in one reply.

8. Customizable items & accessories

Warranty	12 months against material and workmanship defects from shipment.

10. FAQ

Does ASTM B265 cover strip as well as sheet and plate?

Yes. B265 covers strip, sheet and plate in the same grades. Strip is the narrow-width coiled form used for stamping and forming; sheet is flat and ≤ 4.76 mm; plate is flat and ≥ 4.76 mm. All three carry the same grade chemistry and mechanicals.

Which grade for a reducing acid?

Use Grade 7 (Pd) or Grade 12 (Mo/Ni). Grade 12 gives near-equal corrosion resistance in most reducing acids at roughly 30–40 % lower cost because it carries no palladium — pick Gr12 unless the spec mandates Gr7. Plain Gr2 would be attacked.

What is the sheet-versus-plate line?

ASTM B265 sets it at 4.76 mm (3/16 in). At or below is sheet (cold-rolled, tight tolerance); at or above is plate (hot-rolled). For formed or thin parts use sheet; for structural blocks use plate.
