Titanium Grade 1-2-3-4 Electropolished Pipe for Chemical processing
Oct 22, 2025
commercially pure (CP) Titanium Available in five distinct grades (1, 2, 3, 4 and 7), Titanium is classified by its corrosion resistance, ductility, and strength. CP Ti Gr. 1 has the highest corrosion resistance, formability, and lowest strength, whereas, CP Ti Gr. 4 offers the highest strength with moderate formability. The most desirable feature of our CP Ti is its ability to osseointegrate within the human body. Titanium also offers a higher strength-to-weight ratio and increased corrosion resistance compared to the stainless steel alloys, thus making it an attractive choice for medical applications.
Grade 1 titanium is the first of four commercially pure titanium grades. It is the softest and most ductile of these grades. It possesses the greatest formability, excellent corrosion resistance and high impact toughness.
Because of all these qualities, Grade 1 is the material of choice for any application where ease of formability is required and is commonly available as titanium plate and tubing. These include:
Chemical processing , Chlorate manufacturing, Dimensional stable anodes, Desalination
Architecture, Medical industry, Marine industry, Automotive parts, Airframe structure
Grade 2 titanium is called the "workhorse" of the commercially pure titanium industry, thanks to its varied usability and wide availability. It shares many of the same qualities as Grade 1 titanium, but it is slightly stronger. Both are equally corrosion resistant.
This grade possesses good weldability, strength, ductility and formability. This makes Grade 2 titanium bar and sheet are the prime choice for many fields of applications:
Architecture, Power generation, Medical industry, Hydro-carbon processing, Marine industry
Exhaust pipe shrouds, Airframe skin, Desalination, Chemical processing, Chlorate manufacturing
Grade 3 Titanium Parts is least used of the commercially pure titanium grades, but that does not make it any less valuable. Grade 3 is stronger than Grades 1 and 2, similar in ductility and only slightly less formable – but it possesses higher mechanicals than its predecessors.
Grade 3 is used in applications requiring moderate strength and major corrosion resistance. These include:
Aerospace structures, Chemical processing, Medical industry, Marine industry
Grade 4 Titanium is known as the strongest of the four grades of commercially pure titanium. It is also known for its excellent corrosion resistance, good formability and weldability.
Though it is normally used in the following industrial applications, Grade 4 has recently found a niche as a medical grade titanium. It is needed in applications in which high strength is required:
Airframe components, Cryogenic vessels, Heat exchangers, CPI equipment
Condensor tubing, Surgical hardware, Pickling baskets
