Grade 2 Titanium Wire for Springs and Fasteners: Selection Guide
- Grade 2 Titanium Rod
Grade 2 titanium wire may be evaluated for an industrial spring or fastener when the component’s load, environment and fabrication requirements are defined. The wire grade alone does not establish spring stiffness, fatigue life, corrosion life or an allowable operating-temperature range.
Start with the component design
For a spring, specify wire diameter, coil geometry, load and deflection, operating temperature and expected cycles. For a fastener, provide the drawing, thread or forming requirements, joint load and service environment. Material condition and manufacturing can change performance, so verify the finished component against its design requirements.
| Requirement | Information to establish |
|---|---|
| Material | Grade, wire standard and edition, diameter, tolerance and condition. |
| Forming | Coiling or heading process, tooling, surface and inspection requirements. |
| Fatigue | Loading history, component geometry, environment and acceptance test. |
| Corrosion | Medium, concentration, temperature, joints and contact materials. |
Wire specification and processing
Grade 2 is unalloyed titanium, UNS R50400. ASTM B863 covers Grade 2 titanium wire within its scope; state the agreed edition and any additional requirements. Select the delivery condition for the intended coiling, forming or heading operation. Set process parameters through representative trials rather than assuming a universal drawing reduction, tooling size or heat-treatment schedule.
Where welding is involved, specify the applicable filler classification and qualified joining procedure. General material conformity does not replace the finished-part inspection or application-specific testing.
Performance and medical boundaries
Compare fatigue or corrosion results only when the specimens, loading and environment are relevant. Claims of a fixed number of years, guaranteed resistance to cracking or MRI safety require evidence for the actual component. For medical-device use, confirm the applicable material specification and independently evaluate the finished device; ASTM F67 covers Grade 2 in specified forms for surgical implant manufacture, within its scope.
Frequently asked questions
Does a wire certificate guarantee spring life?
No. The finished spring’s geometry, process, loading and environment require separate assessment.
Is Grade 2 always better than stainless steel?
No. Compare the exact grades, component design and operating conditions.
