| Titanium Grades Comparison |
|---|
| Commercially Pure Titanium | Description |
|---|
| Grade 1 | Grade 1 has high weldablity and excellent formability and formablity. It is one of the softest grades with high ducility while maintaining impact toughness. It is uesd widely in desalination and chemical processing facilities. |
|
|
| Grade 2 | Grade 2 is dubbed the "workhorse" and "garden variety" grade for industrial work and excellent resistance to corrosion. It also has excellent weldability, ductility and cold formability ratings with moderate strength. It is widely used ofr architecture and power generation. |
|
|
|
| Grade 3 | Grade 3 is a bit stronger than what you will find with grade 2, with major corrsion resistance and good weldability. It has reasonable formability and ductility and is widely used in aerospace, chemical processing, and marine applications. |
|
|
| Grade 4 | Grade 4 has reasonable weldability, reduced ductility and good cold formability. Being one of the strongest grades, it's more common uses are airframe parts, heat exchangers and CIP equipment. |
|
|
| Alloy Titanium | Description |
|---|
| Grade 5 | Grade 5 is one of the most commonly used alloys. With its high strenght and heat tratable aspects (ability to be used up to 400° Celsius)this grade has it all. It is widely used in aircraft turbines, engine components, aircraft structural, and high performance auto parts. |
|
|
| Grade 7 | Grade 7 has mechanical properties similar to grade 2 with excellent fabricability and weldability. It is also the most resistant to corrosion in reducing acids. It is highly used in chemical. Processing and production equipment components. |
|
|
| Grade 9 | Grade 9 has medium strength that falls between Grade 4 and Grade 5. It has excellent corrosion resistance and is used in Aerospace and Industrial applications. Grade 9 Titanium can be used at higher temperatures than Grades 1 through 4. Grade 9 titanium has good cold rolling properties. |
|
|
|
| Grade 11 | Grade 11 is highly resistant to corrosion has similar physical and mechanical properties to Titanium CP Grade 2. It has excellent weldability and fabricability. |
|
| Grade 12 | Grade 12 is similar to Grade 2 and Grade 3 except that Titanium Grade 12 has 0.3% molybdenum and 0.8% nickel. This offers enhanced corrosion resistance. It has similar strength to the 300 series steels. With excellent formability, hogh weldability and fabricability. And it isCommon used in heat exchangers, marine and airfare components as well as chemical manufacturing. |

|
|
| Grade 16 | Grade 16 is a titanium alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. It has a moderately high thermal conductivity among wrought titaniums. In addition, it has a moderately high ductility and a moderately low tensile strength. |
|
|
|
| Grade 17 | Grade 17 is a titanium alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. It has a moderately high electrical conductivity among wrought titaniums. In addition, it has a fairly low tensile strength and the highest thermal conductivity. |
|
|
|
| Grade 23 | Grade 23 is similar to Grade 5 but has lower oxygen, nitrogen and iron. It has better ductility and fracture toughness that Grade 5. It is anextra low interstitial version of a titanium alloy with improved ductility. It is widely used in biomedical implants but also has beend found very useful in airframe coomponents, ballistic armor and offshore hydrocarbon production. |
