Commercially Pure Titanium Grades

Dec 11, 2017

Grade 1

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

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

This grade 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

Grade 4 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
