Introduction: 

Titanium is a metal known for its excellent strength-to-weight ratio. It’s a strong, low-density metal that’s also ductile (particularly in an oxygen-free environment), glossy, and metallic-white in appearance. It’s valuable as a refractory metal because of its comparatively high melting point of over 1,650 °C (3,000 °F). In comparison to other metals, it is paramagnetic and has a low electrical and thermal conductivity. When titanium is chilled below its critical temperature, it becomes superconducting. At Prashaant Steel and Alloys you will get to see different Titanium Products and their grades.

Titanium Grades

  • Grade 1

The first of four commercially pure titanium grades are Grade 1. It is the most supple and ductile of the three grades. It has the best formability, corrosion resistance, and impact toughness of any material. Grade 1 is the material of choice for any application requiring ease of formability, and it is usually 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 known as the “workhorse” of the commercially pure titanium industry due to its wide range of applications and widespread availability. It has a lot of the same characteristics as Grade 1 titanium, but it’s a little bit stronger. Both are resistant to corrosion. Weldability, strength, ductility, and formability are all strong features of this grade. 

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 is the least common of the commercially pure titanium grades, yet that does not diminish its worth. Grade 3 is stronger than Grades 1 and 2, has similar ductility, and is just slightly less formable than its predecessors, but has higher mechanical properties.

Grade 3 is utilized in applications that require moderate strength as well as significant corrosion resistance.

These include:

  • Aerospace structures
  • Chemical processing
  • Medical industry
  • Marine industry 
  • Grade 4

Grade 4 is the most powerful of the four commercially pure titanium grades. It’s also noted for its good formability and butt weldability, as well as its remarkable corrosion resistance.

Grade 4 titanium has recently established a niche as medical-grade titanium, despite its usual industrial applications. It’s required in situations where considerable strength is required, such as: 

  • Airframe components
  • Cryogenic vessels
  • Heat exchangers
  • CPI equipment
  • Condensor tubing
  • Surgical hardware
  • Pickling baskets

Titanium Alloys

  • Grade 7

Grade 7 is mechanically and physically identical to Grade 2, with the exception that it contains the interstitial element palladium, making it an alloy. Grade 7 is the most corrosion-resistant of all titanium alloys, with outstanding weldability and fabricability. It is more corrosion resistant in reducing acids.

Grade 7 is used in chemical processes and components of production equipment.

  • Grade 11

Grade 11 is essentially identical to Grade 1, with the exception that a small amount of palladium has been added to improve corrosion resistance, making it an alloy. In chloride conditions, this corrosion resistance is important for preventing crevice erosion and decreasing acid. 

Optimal ductility, cold formability, usable strength, impact toughness, and outstanding weldability are among the other beneficial qualities. This alloy is suitable for the same titanium applications as Grade 1, particularly if corrosion is a concern, such as:

  • Chemical transformations
  • Desalination 
  • Applications in the marine environment

How to Choose the Right Titanium Grades

There are several degrees of commercially pure titanium and titanium alloys available, and you must ensure that you receive the proper forms and grades to finish your job effectively. While all grades are corrosive-resistant, robust, and light, some key variances could affect the ultimate results.

When selecting a titanium grade, keep in mind how the metal will be used, the circumstances it will be exposed to, and the size of the titanium pieces. There are four classes of pure-grade titanium, each with its own set of qualities that make it suited for diverse purposes.

A list of commercially pure titanium and many of the most popular alloys, as well as the most typical product shapes and applications, is provided below. Understanding these characteristics and how they affect your project can aid you in selecting the best titanium grade for the job. 

Other Titanium Alloys and Products 

Though the most common titanium alloys were described above, numerous other titanium alloys are less well-known and employed. There are some other products such as Titanium Buttweld Fittings, Titanium Flanges, Titanium Fasteners, and other Titanium alloys which range from grade 1 to grade 38, with different properties and applications depending on the alloy metals.

Consider the environment in which the component will be used, the function of the part, and the size of the desired part when choosing titanium or titanium alloy for your project.
