Grade 2 Titanium Bar: Material Selection and Uses
- Gr2 Titanium Bar
Grade 2 titanium bar is an unalloyed titanium product used for components where its specified properties and service compatibility meet the design. Its value depends on the actual loads, environment, fabrication and documentation requirements; it is not automatically the best grade for every application.
Material identity and specification
Grade 2 is UNS R50400. ASTM B348/B348M covers annealed titanium bars and billets, including Grade 2. Define the applicable edition, diameter, length, condition, tolerance and surface. Confirm the chemical and mechanical acceptance values against the contracted specification and delivered-lot records. A bar standard does not automatically specify tube, sheet or wire.
Choosing the grade
Compare Grade 2 with other grades using properties required for the actual part and the corresponding material condition. A strength figure from another form or grade cannot establish the working load, fatigue life or service temperature of a finished component.
| Requirement | Selection information |
|---|---|
| Mechanical duty | Geometry, loads, temperature, condition and applicable test records. |
| Corrosion | Medium, concentration, contaminants, temperature, crevices and exposure. |
| Fabrication | Machining, forming, welding, inspection and finished tolerances. |
| Records | Material certificate, lot traceability and agreed tests. |
Service and fabrication
Bar may be machined into shafts, fittings or fasteners when the design permits. Chemical and marine applications need a specific corrosion assessment; a single corrosion rate is not applicable to all conditions. Welding requires suitable cleaning, shielding and a qualified procedure where specified. Establish machining and forming parameters for the actual material and part.
For medical device manufacture, identify the appropriate material specification and assess the finished device separately. A Grade 2 designation does not establish biological safety, clinical performance or regulatory approval.
For a broader procurement framework, see the Grade 2 titanium rod selection guide.
Frequently asked questions
Does Grade 2 have a universal maximum service temperature?
No. Temperature, time, load and the applicable design rules must be assessed together.
Does a bar certificate qualify a finished device?
No. Material acceptance and finished-device qualification are separate.
