Hexagon Titanium Bar Ready Stock Baoji | Gr2 / Gr5 (TC4), Cold-Drawn h11/h9, AF-Traceable

Meta Description: Hexagon titanium bar ready stock in Baoji — Gr2/TA2 & Gr5(TC4), ASTM B348, cold-drawn h11/h9, AF 6–60mm, annealed, straightness ≤0.5–1mm/m, cut-to-length, EN 10204 3.1 heat-traceable. For hex bolts, nuts, valve stems, marine fittings. Quote in 24h.

Overview — A Hex Bar Is Bought by "Across Flats", Not Diameter

First thing procurement gets wrong: quoting a hex bar by "Φ". Hex stock is specified by Across Flats (AF / SW) — the distance between two parallel flat sides. Get AF wrong and the nut doesn't index, the wrench slips, the bar feeder jams.

We keep Gr2/TA2 and Gr5/TC4 hexagon bar in rotating stock out of Baoji Titanium Valley. Cold-drawn for small/mid AF (clean flat, tight tolerance, straight), hot-rolled/forged for large AF. Annealed default — stress-relieved so it stays straight after heavy CNC removal.

Why Hex Blank Instead of Milling From Round

• Less chip, less scrap: pre-formed hex skips the hex-milling op — titanium at $30+/kg, scrap is real money
• Faster cycle: Swiss/CNC lathe clamps the flat, turns thread/shank in one chuck
• Better grain at corners: cold-drawn grain flow follows the flat → torque resistance on final fastener
• Wrench-ready geometry: nut/bolt head already shaped; only thread + chamfer left
• Stable clamping: flat sides = no roll-out in collet, lower runout

Stock Scope (Honest)

Honest boundary: cold-drawn h11/h9 dominates SW6–30; SW40+ usually rolled/forged + peeled. Large AF lead stated before PI — no "magic shelf".

Tolerance & Straightness (Write Into Drawing)

Grade Choice for Hex Parts

Chemistry & Mechanical Floor (Annealed, ASTM B348 Ref.)

Gr5 STA route (AMS 4965) ~1170MPa class — PO-stated heat treat, not shelf-default. Interstitial ceilings: Gr2 O≤0.25%, Gr5 O≤0.20%, H≤0.015% (confirm B348 edition).

Cold-Drawn vs Hot-Rolled/Forged — Pick the Route

Traceability & Inspection

• One parent heat → all cut hex pieces carry same heat No.
• EN 10204 3.1, mill-authorized IR, heat-matched chemistry + tensile
• UT per PO (aerospace AMS 4928 level on request)
• Straightness check + AF go/no-go gauge report on request
• 3.2 (SGS/BV/TÜV) witness at buyer cost, PO-fronted — not retro-signed
• Tag = MTC = crate label; no carbon-steel contact in pack

Where Hex Titanium Bar Goes

• Fasteners: hex bolts, nuts, studs (DIN 933 / ISO 4014 / ASME B18 class on request)
• Marine: seawater flange nuts, cathodic-protected bolting
• Valves: hex stem, bonnet nut, coupling body
• Aerospace: lightweight structural bolts, race-shaft hardware
• Motorsport: suspension link bolts, engine bay fasteners
• Oil & gas: chloride-service connectors, HIPPS fittings

Cutting & Packaging for Hex Blanks

• Band-saw with coolant, no heat-tint on flat
• Deburr both ends; chamfer for auto-bar-feeder (30–45°)
• VCI paper + PE sleeve + plywood crate (ISPM-15)
• Desiccant for long-sea; AF label outside + heat No. inside pouch
• Mixed AF in one crate → separated by EPE, per-piece tag

FAQ — Hexagon Titanium Bar Ready Stock Baoji

Q1: Quote by diameter or AF?
A: Always AF (across flats). If you only have "Φ", tell us — we convert, but the PO must show SW to avoid a wrong die.

Q2: h11 cold-drawn ready for Swiss lathe?
A: Yes for common SW6–30. Straightness ≤0.5–1mm/m, deburred/chamfered ends, feeder-compatible. Confirm collet size before shipment.

Q3: Gr2 or Gr5 for my nut?
A: Seawater/corrosion + cost → Gr2. High preload/aero/auto → Gr5. Don't pay TC4 price for a static marine nut.

Q4: Can you cold-head Gr5 hex?
A: Annealed Gr5 heads with controlled O; STA not for cold-heading. Heading trial = same-heat sample first.

Q5: Large AF like SW50–80?
A: Rolled/forged + peeled; not cold-drawn tolerance class. Lead quoted honest, not "shelf h11".

Q6: MTC after cutting still valid?
A: Yes — 3.1 ties cut pieces to parent heat; AF gauge report on request.

Q7: STA hex blank?
A: PO-stated heat treat, heat-confirm. Annealed is default for machining/heading.

Q8: Implant hex fastener?
A: Industrial Gr5 ≠ implant. Implant path = Gr23 ELI + F136 chain, separate PO, DMR docs.

Q9: Dispatch?
A: In-stock AF + PO before 3 PM China time → same-week cut/dispatch. Sea FOB Shanghai; air for line-down at buyer cost.

Q10: Trial lot?
A: 1–2 short cutoffs from same heat at courier cost, deductible from bulk PO.
