The performance of industrial pure titanium tubes of different grades may vary greatly. How to choose the appropriate grade for industrial use? What are the differences and application scenarios of these grades?
1.Gr1 titanium is the first of four industrially pure titanium grades. It is the softest and most malleable of these grades. It has maximum formability, excellent corrosion resistance, and high impact toughness.
Because of all these qualities, Gr1 is the material of choice for any application that requires easy formability, often as titanium sheet and titanium tubing. These include chemical processing, chlorate manufacturing, dimensionally stable anodes, desalination, construction, medical industry, marine industry, automotive components, airframe structures.
2. Gr2 Titanium Due to its diverse availability and wide availability, Gr2 titanium is known as the "workhorse" of the commercially pure titanium industry. It shares many of the same qualities as Gr1 titanium but is slightly stronger. Both are equally resistant to corrosion.
This grade has good weldability, strength, ductility, and formability. This makes Gr2 titanium rods and sheets the first choice for many applications: construction, power generation, medical industry, water carbon processing, marine industry, exhaust pipe guards, fuselage skins, desalination, chemical processing, chlorate manufacturing.
3. Gr3 Titanium This grade uses the least commercially pure titanium grade, but this does not make it less valuable. Gr3 is stronger than Gr1 and Gr2, with similar ductility and only slight formability - but it has higher mechanical properties than its predecessors.
Gr3 is used in applications requiring moderate strength and primary corrosion resistance. These include aerospace structures, chemical processing, medical industry, marine industry.
4.Gr4 is considered to be the strongest of the four types of commercially pure titanium. It is also known for its excellent corrosion resistance, good formability, and weldability.
While it is commonly used in the following industrial applications, Grade 4 has recently found a niche in medical-grade titanium. It is needed in applications that require high strength: airframe components, cryogenic vessels, heat exchangers, CPI equipment, condenser tubes, surgical hardware, pickling baskets.
