What Are Titanium Grade 2 Round Bars?
Titanium Grade 2 Round Bars are manufactured from commercially pure (CP) titanium containing a minimum of 99% titanium. The alloy designation ‘CP2’ (also written Titanium Gr 2, UNS R50400, or Werkstoff Nr. 3.7035) represents the most widely used CP titanium grade owing to an excellent balance of moderate strength, outstanding cold-workability, and superior corrosion resistance in a broad range of aggressive media.
Within the CP titanium family, Grade 2 occupies the mid-range stronger than Grade 1 (R50250) yet easier to form than Grades 3 and 4. The key interstitial elements that govern its properties are oxygen (max 0.25 wt.%) and nitrogen (max 0.03 wt.%). A higher oxygen content increases strength but reduces ductility; Grade 2 is deliberately specified at a controlled oxygen ceiling to deliver both adequate yield strength and the ductility required for complex machining, cold-forming, and orbital welding.
Bars are produced to ASTM B348 / ASME SB348 and may additionally conform to AMS 4902, AMS 4921, AMS-T-9046, MIL-T-81556, and ASTM F67 as applicable to end-use industry.
Titanium Grade 2 vs Titanium Grade 5 – Key Differences
Procurement teams in the aerospace and chemical industries frequently face the choice between Titanium Grade 2 (CP) and Titanium Grade 5 (Ti-6Al-4V). The table below summarises the critical technical distinctions:
| Property | Titanium Grade 2 (CP2) | Titanium Grade 5 (Ti-6Al-4V) |
|---|---|---|
| Alloy type | Commercially pure (α) | α-β alloy |
| UNS | R50400 | R56400 |
| Min. tensile strength | 345 MPa (50 ksi) | 895 MPa (130 ksi) |
| Min. yield strength | 275 MPa (40 ksi) | 828 MPa (120 ksi) |
| Density | 4.51 g/cm³ | 4.43 g/cm³ |
| Corrosion resistance | Excellent (esp. oxidising/chloride) | Good – lower than Gr 2 in HNO₃ |
| Cold formability | Excellent | Limited – hot forming preferred |
| Weldability | Excellent – all fusion methods | Good – requires post-weld heat treat |
| Biocompatibility | ASTM F67 – implant grade | ASTM F136 – implant grade |
| Typical applications | Chemical, marine, desalination | Aerospace structural, high-stress parts |
| Relative cost | Lower | Higher (~2.5× Gr 2) |
Use Titanium Grade 2 where maximum corrosion resistance, ease of fabrication and cost efficiency are priorities. Specify Titanium Grade 5 Round Bars where structural strength and fatigue resistance are the overriding requirements.

Corrosion Resistance of Titanium Grade 2 Bars
Titanium Grade 2 Round Bars derive their corrosion resistance from a stable, self-regenerating TiO₂ (titanium dioxide) passive film that forms instantly on any fresh metallic surface exposed to air or moisture. This mechanism provides protection across a very wide pH range and in many aggressive media where stainless steels and nickel alloys fail.
Performance in Specific Media
| Environment / Media | Resistance | Notes |
|---|---|---|
| Seawater & brackish water | Excellent | No pitting; preferred for offshore hardware |
| Oxidising acids (HNO₃, aqua regia) | Excellent | Resists attack up to concentrated HNO₃ |
| Chloride solutions | Excellent | Passive film stable up to ~260 °C in chlorides |
| Hydrochloric acid (HCl) | Poor at high conc. & temp. | Add inhibitor; consider Gr 7 (Pd-doped) for HCl service |
| Sulphuric acid (H₂SO₄) | Fair at low conc. | Grade 7 or 12 preferred above 5% H₂SO₄ |
| Crevice corrosion | Good | Susceptible in concentrated hot brines above 70 °C; design for flow |
| Hydrogen embrittlement | Low risk – good | Avoid cathodic protection coupling below −0.7 V SCE |
| Organic acids (acetic, citric) | Excellent | Widely used in food-grade chemical plant |
Welding Titanium Grade 2 Round Bars
Titanium Grade 2 is one of the most weldable forms of titanium. Its low interstitial content and single-phase (α) microstructure mean it does not experience the post-weld embrittlement that affects some other titanium alloys. The following guidelines are critical for sound welds:
- Shielding gas: High-purity argon (99.998% min.) or helium. Dual shield both the weld puddle and the trailing root side. Inadequate inert gas coverage results in oxide discolouration — the internationally recognised colour criterion is: silver/bright = clean; gold/yellow = marginal; blue/grey/white = reject and rework.
- Filler wire: AWS A5.16 ERTi-2 (matching grade). ERTi-1 (Gr 1) may be used for joints where dilution will raise the deposit strength sufficiently.
- Pre-weld cleaning: Degrease with acetone or isopropyl alcohol. Mechanically clean (stainless steel brush dedicated to titanium only) and wipe immediately before welding. Contamination from steel tools transfers iron, which initiates galvanic corrosion.
- Welding processes: GTAW/TIG (preferred), Plasma arc welding (PAW), Electron beam welding (EBW), Laser beam welding (LBW). MIG/GMAW is acceptable for non-critical weld repairs on thick sections using pure argon shielding.
- Post-weld heat treatment (PWHT): Generally not required for CP Grade 2. Stress-relief anneal at 480–595 °C for 1–4 hours in an inert atmosphere improves dimensional stability of complex fabrications.
- Note on dissimilar metal welding: Titanium may be electron-beam or explosion-bonded to stainless steel or copper alloys. Direct fusion welding to steel produces brittle intermetallics; always use a transition piece or clad product.
Heat Treatment of Titanium Grade 2 Bars
Because Titanium Grade 2 is an alpha-phase alloy, it cannot be strengthened by precipitation hardening or martensitic transformation. The following thermal cycles are used in manufacturing and fabrication:
| Treatment | Temperature Range | Hold Time | Purpose |
|---|---|---|---|
| Mill anneal | 700–785 °C | As required | Recrystallise after cold working; restore ductility |
| Stress relief anneal | 480–595 °C | 1–4 hrs | Reduce residual stresses post-forming/welding |
| Recrystallisation anneal | 925–955 °C (1 hr) | 1 hr | Full softening; maximum corrosion resistance |
| Vacuum anneal | 700–800 °C in vacuum | 1–3 hrs | Avoids surface oxidation on precision bars |
All heat treatment must be carried out in a vacuum or inert-gas atmosphere furnace. Titanium absorbs oxygen, nitrogen, and hydrogen above 500 °C, causing case hardening (α-case) that degrades fatigue life and toughness. Our bars undergo SCADA-controlled annealing with documented time-temperature records supplied with each MTC.

Applications of Titanium Grade 2 Round Bars
The combination of corrosion resistance, biocompatibility, and structural integrity makes Titanium Alloy Grade 2 Round Bars the material of choice across the following industries:
- Chemical Processing: Reactors, heat exchangers, distillation columns, pumps, and piping handling nitric acid, chromic acid, organic acids, and halide-containing process streams. Titanium Gr 2 Rods machined into valve stems and pump shafts outperform stainless steel 316L in oxidising acidic service by a factor of 10× or greater in corrosion rate.
- Marine & Offshore: Propeller shafts, seawater cooling system components, torpedo tubes, hull fittings, submarine hardware, and desalination plant components. The passive TiO₂ film remains intact in full seawater immersion indefinitely unlike copper alloys or stainless steel, titanium does not biofoul or suffer accelerated crevice attack in aerated seawater at ambient temperatures.
- Aerospace & Defence: Hydraulic tube fittings, fasteners, airframe bulkheads where light weight and moderate strength are required. ASTM B348 Gr 2 Rods are approved to AMS 4902 and AMS 4921 for use in commercial aviation and defence applications where traceability to raw material origin is mandatory.
- Medical & Dental: Bone screws, orthopaedic implants, spinal fusion rods, dental abutments, and surgical instrumentation. Grade 2 titanium is approved to ASTM F67 for surgical implant use. Its osseointegration properties are superior to stainless steel, and it is MRI-compatible — generating no artefacts in magnetic resonance imaging.
- Power Generation & Desalination: Condenser tubing support structures, cooling water intake screens, flash evaporator baffles, and multi-stage flash (MSF) plant hardware. Titanium’s imperviousness to biologically influenced corrosion (BIC) from sulphate-reducing bacteria makes it the engineered choice for once-through seawater cooling systems.
- Pulp & Paper Industry: Bleaching plant equipment, chlorine dioxide handling systems, and washers operating in hot bleach filtrate. Titanium Grade 2 Bars offer 20+ year service life in environments that destroy super-austenitic stainless steels within months.
