Overview — Buying a Full 6m Bar When You Need 320mm Is Waste

CNC shop, prototype bay, maintenance crib, fastener workshop — most buyers don't want a 6-meter parent bar. They want one traceable blank that drops into the lathe. That's what "cut to length from inventory" means here: pull a heat-confirmed parent bar off the shelf, log the heat, saw to your drawing length, deburr, mark, cert — no full-bundle minimum, no mystery heat.

Gr2/TA2 and Gr5/TC4 common diameters rotate in stock. Saw cut is a sizing operation, not a finish-machining operation — we say where the tolerance stops and where a facing op starts, so the workshop doesn't find out mid-job.

What "From Inventory" Covers (Honest)

No "every diameter forever on shelf" bluff — common sizes confirmed by heat before PI.

Saw Cut Tolerance — What a Saw Can Hold

Rule: sawing sizes; machining finishes. If the end face seats a bearing or takes a weld root, write "face both ends" in the PO — don't assume a saw cut is weld-ready.

Diameter Tolerance — Pick the Class Before Cutting

Don't order h7 and expect black-bar price. Tolerance class = grinding op = cost. We quote the class, not a promise.

Traceability Through the Cut (The Part Most Suppliers Break)

• One parent bar = one heat number. Cut into 20 pieces → all 20 still tie to that heat
• Each piece tagged / laser-marked (on request): grade + heat No. + PO ref
• MTC 3.1 references cut quantity + parent heat — not "generic cert"
• Tag = MTC = packing list = crate label
• Mix-heat-after-cut is unrecoverable — we lock traceability before the blade drops

Technical Baseline (Annealed)

STA Gr5 (AMS 4965 route) ~1170/1100 MPa class — PO-stated heat treat, not shelf-default.

Cutting Workflow (What Happens After PO)

1. Confirm grade + dia + heat from rotating stock
2. Log parent heat No. before cut
3. Band-saw (bi-metal / carbide per section), flood coolant, no burn
4. Deburr ends; chamfer if specified
5. Straightness check (1mm/m typical; tighter on request)
6. Mark heat No. / PO ref on each piece (if requested)
7. MTC 3.1 drafted against parent heat + cut list
8. VCI paper + PE + plywood crate, desiccant for long-sea

Packaging for Short Blanks (No Mix-Ups)

• Each cut piece separated (foam/EPE), not rattling loose
• VCI anti-rust paper + PE sleeve
• Plywood crate (ISPM-15), strong straps, edge guards
• Heat-number label outside + duplicate inside waterproof pouch
• MTC pouch external; CI/PL/COO with shipment
• No carbon-steel contact in pack or finish

When to Add a Second Op (Don't Blame the Saw)

• Weld-root face → facing + chamfer
• Bearing seat → h7 ground + face perpendicularity
• Medical/instrument → ELI + clean pack + PMI
• Aerospace → UT per AMS 4928 + dimensional report
• Tight length ±0.05 → saw + CNC facing, quoted as two ops

FAQ — Titanium Round Bar Cut to Length

Q1: Minimum order?
A: No forced full-bar buy. One short blank for prototype accepted; setup/cutting loss still priced fairly, not hidden.

Q2: Saw cut length tolerance?
A: ±0.5–1.5mm by section/length. Tighter = facing op, quoted separate. Saw sizes; machining finishes.

Q3: Is the MTC still valid after cutting?
A: Yes — 3.1 references parent heat + cut list. Piece marking keeps traceability; mix-heat avoided by logging before cut.

Q4: h7 from black bar?
A: No. h7 needs centerless grind. Black/peeled = h9/h11. We quote the route, not a miracle.

Q5: Gr5 STA blanks?
A: PO-stated heat treat, heat-confirm lead. Annealed is shelf-default; STA is a process, not a label.

Q6: Can you face the ends for welding?
A: Yes — saw + CNC facing/chamfer. Tell us if end is weld-root or bearing seat; perpendicularity written into op.

Q7: Straightness for CNC?
A: ~1mm/m standard; declare tighter (e.g. 0.5mm/m) in PO, we straighten/check and report.

Q8: Mixed diameters in one crate?
A: Yes — multiple lengths/dias in one shipment, separate marking per piece, one PI, heat map in pack.

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

Q10: Sample blank?
A: 1 cutoff from same heat at courier cost, deductible from bulk PO.
