Titanium Screw —  Export Supply from Baoji Titanium Valley

A titanium screw (bolt, nut, washer) keeps assemblies light and corrosion-free where steel rusts. We stock hex bolts, screws, nuts and washers in Gr2 and Gr5, ASTM F467/F468, M6–M20, with same-day shipping on small orders. Grade 2 for corrosion service; Grade 5 for strength.

1. What Titanium Screw Is and Where It Is Used

Titanium Screw is specified wherever stainless steel fails by corrosion but the part must stay light, strong, or biocompatible. Typical uses:

• marine screws marine and offshore assemblies
• medical fasteners medical-device fastening
• stud bolt chemical-flange stud bolts
• Racing and aerospace lightweight builds
• small-order bolts job-shop spares and prototypes

2. Grade Selection

: Which Titanium to Specify

Grade 2 fasteners — in our bolt-nut-washer set — resist seawater and most chlorides. Grade 5 — hex bolt M6-M10 — adds strength for structural and racing use. Grade 23 — medical fasteners — is the medical-implant fastener. All per ASTM F467 fasteners (ASTM F467/F468).

3. Standards and Dimensions to State on the RFQ

State the governing standard, dimensions, and tolerance up front so quotes are comparable. For Titanium Screw this is usually the relevant ASTM/ASME grade plus your drawing or nominal size. Insist on mill-test certification with heat-number traceability.

4. Titanium Screw in Seawater and Chloride Service

For open, aerated seawater Grade 2 is the default; where the service is reducing, acidic, or has stagnant/creviced zones, step up to Grade 7 (Ti-0.15Pd). Keep flow velocity in the 1–2 m/s band to prevent deposit-driven crevice attack. Related reading: seawater desalination plate and Grade 7 seawater exchanger.

5. The Limitation You Must Know

: Where Titanium Screw Fails

Titanium Fasteners have lower shear and galling tendency under the nut than steel — use proper torque, anti-galling paste, and compatible washers. They are not for strong oxidising acids, dry halogens, or hot concentrated reducing acids. Never pair titanium bolts directly with steel in a wet, conductive environment without isolation — galvanic corrosion attacks the less-noble steel, but the joint can seize.

6. Sizing and Specification Checklist (RFQ-Ready)

1. Grade and temper (Gr2 / Gr5 / Gr7 / Gr12 / Gr23) with the reason above.
2. Dimensions — size, thickness/OD, length, or bore as applicable.
3. Standard (ASTM/ASME/EN) and tolerance class.
4. Quantity and lot — single piece or batch.
5. Surface finish — pickled, polished, machined, or as-rolled.
6. Certificate — EN 10204 3.1 with heat number.
7. NDT requirement — RT/PT/ET where the code demands it.
8. Packing and destination — export packing and freight.
9. Thread standard (metric/UNC) and class
10. Torque spec and anti-galling requirement

7. Common Procurement Mistakes

• Reusing torque values from steel fasteners (titanium yields differently)
• Ignoring galling — no anti-seize on the threads
• Mixing with steel in wet service without isolation

8. Why Titanium Screws Instead of Stainless

In seawater, even 316 stainless fasteners crevice-corrode; marine screws titanium screws stay bright for decades and weigh ~60% less than steel. For racing and medical, Gr5/Gr23 give strength or biocompatibility steel cannot.

9. Why Buy From a Baoji Titanium-Valley Stockist

We hold ~800 tons of titanium and nickel inventory in Baoji, China’s Titanium Valley, and cut to size the same day. That means small MOQ, fast dispatch, and the ability to supply both standard stock and non-standard parts to drawing — without a minimum-lot penalty. Every lot ships with MTC and export documentation.

11. FAQ — Titanium Screw

What titanium screw grades do you stock?

Gr2, Gr5 and Gr23 in hex bolt, screw, nut and washer forms, M6 to M20.

Which for marine use?

Grade 2 titanium screws resist seawater far better than 316 stainless and weigh far less than steel.

Do titanium bolts gall?

They can gall without anti-seize; use proper paste and torque to avoid seizing.

Are they ASTM standard?

Yes — ASTM F467/F468, with EN 10204 3.1 where required.

Can you do small orders?

Yes — small-order bolts same-day ship on small batches.

Medical grade?

Gr23 fasteners are available for medical-device assembly.

Do you export?

Yes — worldwide from Baoji.

Summary: Choose by Service, Not by Habit

Choose Gr2 screw if corrosion service (marine, chemical). Choose Gr5 if strength-to-weight matters (racing, structural). Choose Gr23 if medical. Use anti-seize and isolation if paired with steel in wet service.
