- Product Description
Grade 2 Titanium Bar - High-Purity CP Titanium from China's Titanium Valley
Baoji Jucheng Titanium Industry Co., Ltd., established in 2004 and listed on China's NEEQ since 2017, delivers industrial-grade grade 2 titanium bar engineered to meet ASTM B348 and ASME SB348 standards. Our manufacturing facility maintains approximately 3,000 tons of titanium inventory year-round, ensuring rapid fulfillment for your critical projects. With over 20 years of titanium processing expertise and an annual output of 500+ titanium equipment sets, we produce bars ranging from Φ6mm to Φ450mm in diameter with lengths up to 12,000mm. Our bar features minimum tensile strength of 345 MPa, ≥20% elongation, and density of 4.51 g/cm³—delivering 45% weight reduction versus stainless steel while eliminating stress corrosion cracking in chloride-rich environments.

What Makes Grade 2 Titanium Bar the Industry Workhorse?
Designated as UNS R50400, this commercially pure titanium product solves critical challenges where stainless steel fails.
Your operations face material degradation in wet chlorine, seawater, and oxidizing acids. Traditional alloys suffer pitting corrosion and premature failure. Our bar provides exceptional resistance to these aggressive media while maintaining superior cold formability.
The alpha-phase microstructure offers an optimal balance. You get moderate strength without sacrificing ductility. Unlike Grade 5 alloys requiring pre-heat treatment, our bars enable direct cold forming and complex fabrication—reducing your production time and costs.

Manufacturing Process Excellence
Our vacuum melting process ensures material purity. Each grade 2 titanium bar undergoes:
· Vacuum melting for contamination control
· Precision forging for grain refinement
· Hot rolling or rotary forging for dimensional accuracy
· Centerless grinding or turning for surface finish
· Straightening and surface treatment per your specifications
Our 120,000-square-meter facility integrates R&D cooperation with Northwest Nonferrous Metals Research Institute and Tsinghua University. This partnership strengthens quality control across every production stage.
Chemical Composition Advantages
Element | Content (%) |
Titanium (Ti) | Balance |
Iron (Fe) | ≤ 0.30 |
Oxygen (O) | ≤ 0.25 |
Carbon (C) | ≤ 0.08 |
Nitrogen (N) | ≤ 0.03 |
Hydrogen (H) | ≤ 0.015 |
The controlled oxygen content delivers strength without compromising weldability. Low iron levels maximize corrosion resistance in your chloride-exposed applications.

FAQ
Q: Why choose grade 2 over Grade 5 titanium alloy?
A: Grade 2 offers superior cold formability and weldability without pre-heat treatment. It's cost-effective for corrosion-critical applications not requiring Grade 5's higher strength.
Q: What's your minimum order quantity for custom lengths?
A: Our 3,000-ton inventory enables flexible MOQs. Custom lengths up to 12,000mm are available—contact us for project-specific requirements.
Q: How do you ensure consistency across large orders?
A: Our professional quality inspection team implements batch traceability. Each bar includes material certifications per ASTM B348 standards, backed by our 41 utility model patents.
Q: What surface finishes work best for welded assemblies?
A: We recommend pickled or turned surfaces for welding applications. The clean surface enhances fusion quality and reduces contamination risks.
