Our CP Grade 2 tubes have a density of 4.51 g/cm3, which is 45% lower than ferrous alloys. It is a medium-strength alloy with a typical yield strength of 352 MPa. The alloy has good ductility, formability and welding properties. The addition of iron and oxygen improves strength and formability. CP Grade 2 exhibits similar performance qualities to Grade 1, including excellent corrosion resistance under oxidizing conditions. However, this titanium tube is stronger than Grade 1 titanium tube.
Grade 2 Titanium Tubes are commercially pure titanium with a good balance between strength and ductility. The material has good toughness. It is the most commonly used titanium alloy due to its high strength, weldability and corrosion resistance. Its high ductility and formability make it the alloy of choice for piping systems, heat exchangers, reaction and pressure vessels, and flue gas desulfurization systems. Grade 2 titanium alloys are used in a variety of industries, including chemical processing, petrochemical processing, aerospace and marine.

This is the most often used titanium tube for industrial applications, providing a superb balance of moderate strength and reasonable ductility. It offers excellent corrosion resistance in both highly oxidising and slightly reducing conditions (including chlorides). It provides good corrosion protection in the chemical and offshore industries, as well as aircraft manufacture, where strength and ease of forming are required. It’s also utilised in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.

Our services
- We customise your grade 2 titanium tubes to your specifications, certify them with various certifying organisations (e.g., TÜV Rheinland or DNV), and begin upgrading titanium semi-finished products for the corresponding applications.
- We will be delighted to advise and explain what you need to know when obtaining titanium tubes, as well as which criteria you should pay particular attention to while producing the components.
- If you have long-term delivery responsibilities, you can enter into a framework agreement with Daxun. We guarantee prices and quantities within specified dates.
- Benefit from our extensive knowledge in the worldwide procurement industry. Since 2001, we have served small, medium-sized, and large businesses at home and abroad.
- Have you got any questions? Our service centre would be delighted to answer any queries you have about finished titanium tubes and unusual materials. We look forward to hearing from you.
The grade of titanium alloy you need depends on the project you are working on, as each grade has different benefits.
All grades of titanium alloy are extremely strong and corrosion resistant, which means they will continue to work well in the harshest conditions.
The higher grades of titanium alloy (5-12) are alloys designed for specific benefits. For example, grade 12 titanium alloy has excellent heat resistance, making it a perfect choice for shell and tube heat exchangers, hydraulic piping, and chemical industry equipment.
Grades 1-4 are pure titanium alloys, and they are a perfect choice if you need a weldable, ductile material for piping systems and tubing. You will find lower grades used in the marine and industrial industries.
If you are starting a project and are unsure which grade of titanium alloy is best for you, contact us today; we are more than happy to help you.
At DAXUN, we offer a wide range of titanium alloy grades from grade 1 to grade 12.
Grades 1-4 are pure titanium, while higher grades are alloys.
Alloy grades are popular for their high strength-to-weight ratio.
The most commonly used titanium alloy grade we find is grade 5. While still high in titanium, this grade is one of the most reliable because it can withstand temperatures up to 600°F and withstand extreme conditions.
Higher grades are favored by industries such as aerospace and marine industries for their wear and corrosion resistance.
Conversely, lower grades are primarily used for welding due to their lower strength.
To learn more about the differences between different grades of titanium alloy, call +86 13382898899 today to speak directly with our experts.
While the grade of titanium does increase the cost slightly, the total cost is primarily determined by the shape and form of titanium you require.
At DAXUN, we offer a wide range of titanium products, including pipe/tubes, tubes, coils and bars. The length, width and quantity of each item you require will affect the amount you pay at checkout.
Unfortunately, it is difficult to come up with a price online without knowing much about your project and what the titanium will be used for.
Fortunately, our team of experts are always here to help and advise you on your titanium needs. By sending an email to [email protected], we will be able to get back to you with some advice and an accurate quote.
