TA2 Titanium Sheet for Heat Exchanger Fabrication | Gr2 ASTM B265 Cut-to-Size

Meta Description: TA2 (Gr2) titanium sheet for heat exchanger fabrication from Baoji ready stock. ASTM B265, 0.5–50mm, cut-to-size, MTC EN 10204 3.1, same-day dispatch on confirmed orders. Quote within 24h.

Overview

TA2 (commercially pure titanium, equivalent to ASTM Gr2 / UNS R50400) is the most widely specified grade for heat exchanger fabrication. We are a Baoji-based titanium inventory holder with 800 tons total titanium stock, including ~400 tons of Titanium Plate/sheet. For heat exchanger manufacturers, we supply TA2 sheet from ready stock, cut to drawing or dimension list, with full mill traceability and export packing. This page covers grade rationale, thickness selection, fabrication notes, cutting capability, and ordering steps — written for procurement engineers, not for keyword stuffing.

Why TA2 for Heat Exchanger Fabrication

TA2/Gr2 sits in the sweet spot of corrosion resistance, formability, and cost:

• Corrosion resistance: Stable oxide film resists seawater, chlorides, wet chlorine, nitric and organic acids — no corrosion allowance needed in most chloride services
• Formability: Elongation ≥20% (annealed), suitable for deep drawing, bending, and stamping of plate-heat-exchanger cassettes
• Weldability: TIG/MIG/PAW weldable with CP-Ti filler; argon backing recommended to avoid oxidation
• Weight: Density 4.51 g/cm³ — about 60% of steel, reduces skid and support load
• Traceability: Every sheet carries heat number, MTC EN 10204 3.1, cross-checked before dispatch

Note: For strong reducing acids at elevated temperature, Gr7 (Pd-added) or Gr12 may be proposed. We review medium data before substituting grade.

Technical Parameters

Cutting for HX Fabrication

• Shearing: ≤12mm straight rectangles for baffle plates and shell blanks
• Waterjet: 0.5–50mm, ±0.2mm, no heat-affected zone — preferred for tube sheets and profiled cassettes
• Plasma: 12–50mm thick plate, economic option for tube sheets
• Band saw: block/blank prep
• CNC drilling: tube hole patterns per drawing (pitch, triangle/square layout)

Send DWG/PDF/STEP. We nest multiple parts from one mother plate and confirm cutting layout before processing.

Tube Sheet & Baffle Plate Service

For shell-and-tube exchanger builders, we handle:

• Tube sheet blank cut from 15–50mm TA2 plate
• Hole drilling per pitch diagram (typical Ø14/19/25mm tube holes, custom on request)
• Chamfering, counterboring, passivation optional
• Baffle plates with segment height per drawing
• Heat-number retention on every cut piece

Surface & Cleanliness for Heat Transfer

• Pickled surface (default): clean oxide removal, matte grey, good for welding
• Bright annealed: lower roughness, better for plate-HX stamping
• Polished (Ra ≤0.8µm on request): reduces fouling, improves heat-transfer contact
• PE film protection for thin sheet during transport and stamping

Export & Packaging

• Interleaved protective film + kraft paper between sheets
• Foam edge guards on cut pieces
• Plywood dividers inside fumigated wooden crate
• Moisture-proof barrier + steel banding
• Flat steel frame for thin sheet (<2mm) to prevent bend
• Marking: grade, heat number, dimensions, PO ref on each piece
• Docs: CI, PL, MTC EN 10204 3.1, COO, MSDS; SGS/BV at buyer cost

Quality Before Dispatch

• Thickness multi-point gauge
• Flatness check (≤3mm/m typical)
• UT for ≥20mm plate
• MTC vs heat-number cross verification
• No substitution without written confirmation
• Spark/XRF check on request for grade verification

FAQ — Heat Exchanger Sheet

Q1: Can TA2 sheet be used for both plate and shell-and-tube exchangers?
A: Yes. Thin sheet (0.5–2mm) for plate cassettes; thick plate (10–40mm) for tube sheets. Same grade, different thickness route.

Q2: What thickness do you keep for tube sheets?
A: Common stock covers 12/16/20/25/30mm TA2 plate. Other thickness cut from mother plate.

Q3: Can you drill tube holes to our pitch drawing?
A: Yes. Send DWG with tube Ø, pitch, layout (triangular/square), and we CNC-drill, chamfer, and mark.

Q4: How do you avoid iron contamination during cutting?
A: Dedicated titanium cutting area, cleaned fixtures, no carbon-steel contact, pickling passivation available post-cut.

Q5: Is annealed condition standard?
A: Yes. TA2 supplied in annealed (M) state unless otherwise specified.

Q6: Can you supply coil for automatic stamping lines?
A: Coil/slit strip available on request for plate-HX stamping; discuss width/inner-diameter with us.

Q7: What is the flatness guarantee for baffle plates?
A: Standard ≤3mm/m; tighter flatness achievable by roller leveling before cutting — specify on enquiry.

Q8: Do you export to Europe/Middle East/Southeast Asia?
A: Yes. FOB Shanghai/Tianjin, CIF/DAP available, full export docs.

Q9: Sample before bulk?
A: 100×100mm coupon from same heat, courier at cost, deductible from bulk order.

Q10: Lead time for a tube-sheet blank?
A: In-stock thickness + waterjet cut + drill: typically 2–3 working days after confirmation; plain shear blank same-day if before 3 PM China time.
