View DetailsTitanium Grade 2
A commercially pure titanium grade offering an excellent balance of ductility, strength, and corrosion resistance for general industrial applications.
Product Overview
Bokang's Titanium Grade 2 is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
Grade 2 titanium is classified as commercially pure titanium and is the most widely used grade among the unalloyed variants. It contains a minimum of 99.2% titanium, with the balance being trace amounts of iron, oxygen, carbon, nitrogen, and hydrogen. This composition provides a balanced combination of moderate strength and excellent formability.
The material is known for its superior corrosion resistance in a wide range of environments, including oxidizing, neutral, and mildly reducing media. Its corrosion resistance is derived from a stable, protective oxide film that forms spontaneously on its surface. Grade 2 exhibits good weldability and can be fabricated using standard techniques, making it a versatile choice for sheet metal work, piping, and components where high strength-to-weight ratio is not the primary driver but reliability and corrosion performance are critical.

Material Selection Guide
How to choose the right titanium wire for your application
1
Evaluate Corrosion Environment
Select Grade 2 for applications involving oxidizing or neutral environments, seawater, and mild chlorides. For more aggressive reducing acids, consider palladium-alloyed grades.
2
Assess Mechanical Requirements
Choose Grade 2 when moderate strength (275-345 MPa yield) is sufficient. If higher strength is needed under the same corrosion conditions, consider Grade 16 (Ti-0.05Pd) or Grade 3.
3
Consider Fabrication Needs
Grade 2 is suitable for projects requiring significant cold forming, bending, or welding. Its ductility simplifies fabrication compared to higher-strength alloys.
4
Review Industry Standards
Ensure the selected form (plate, pipe, fitting) meets relevant ASTM or ASME specifications for pressure vessel or piping code compliance if applicable.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Sponge Production & Compaction
Titanium sponge, produced via the Kroll process, is compacted with master alloy additions into electrodes under controlled atmosphere.
→
Primary Melting
The electrode is melted in a Vacuum Arc Remelting (VAR) furnace to form a primary ingot, ensuring uniform distribution of trace elements.
→
Ingot Conversion
The ingot is forged or hot-rolled at elevated temperatures into intermediate forms like billets, slabs, or blooms.
→
Hot & Cold Working
Intermediate forms are further hot-rolled or extruded into plates, bars, or coils, then cold-rolled/drawn to final dimensions with intermediate anneals.
→
Surface Treatment
Material undergoes pickling in hydrofluic-nitric acid baths to remove scale and oxides, revealing a clean, metallurgically sound surface.
→
Finishing & Inspection
Final cutting, straightening, ultrasonic cleaning, and rigorous inspection (chemistry, mechanical tests, NDT) ensure compliance with specifications.
Frequently Asked Questions
Common questions about pure titanium wire
The primary difference lies in their strength levels, governed by interstitial element content (mainly oxygen). Grade 1 has lower oxygen, resulting in the highest ductility and lowest strength among CP grades. Grade 2 has slightly higher permitted oxygen content, providing increased strength while maintaining good formability, making it the most commonly used general-purpose grade.
Yes, Grade 2 titanium is highly resistant to erosion-corrosion and impingement attack in seawater, even at high flow velocities up to 30-40 m/s. Its protective oxide film reforms instantly if damaged, unlike copper alloys which can suffer from velocity limitations.
Grade 2 titanium exhibits excellent weldability. Gas Tungsten Arc Welding (GTAW/TIG) is the most common method, using matching Grade 2 filler wire (ERTi-2). Critical to success is the use of extensive argon shielding (primary, trailing, and back purge) to protect the molten and hot solidifying metal from atmospheric contamination.
The initial material cost per kilogram for Grade 2 titanium is typically several times higher than for standard 304/316 stainless steel. However, the total lifecycle cost can be lower in aggressive corrosive environments due to titanium's longer service life, reduced maintenance, and elimination of replacement costs.
For continuous service, Grade 2 is generally recommended for temperatures up to approximately 300-350°C (570-660°F). Above this range, its strength decreases significantly, and it can become more susceptible to hydrogen pickup and oxidation. For high-temperature structural applications, titanium alloys like Ti-6Al-4V are preferred.
