Recommendations will appear here.
| Grade | Type | General Characteristics | Typical Applications |
|---|---|---|---|
| Grade 1 | Commercially pure | Excellent corrosion resistance, highest ductility among CP grades | Chemical processing, heat exchangers, formed parts |
| Grade 2 | Commercially pure | Excellent corrosion resistance with higher strength than Grade 1 | Chemical, marine, process equipment |
| Grade 3 | Commercially pure | Higher strength than Grades 1 and 2 | Pressure-containing and industrial components |
| Grade 5 | Ti-6Al-4V | High strength-to-weight ratio | Aerospace, machinery, medical components |
| Grade 7 | Palladium-alloyed CP titanium | Enhanced corrosion resistance | Severe chemical environments |
| Grade 9 | Ti-3Al-2.5V | Good strength, formability and corrosion resistance | Tubing, aerospace and hydraulic systems |
| Grade 12 | Ti-0.3Mo-0.8Ni | Improved crevice-corrosion resistance | Chemical processing and heat exchangers |
| Grade 23 | Ti-6Al-4V ELI | High strength with enhanced fracture toughness and ductility | Medical and aerospace applications |
What is the most common titanium grade? Grade 2 commercially pure titanium is widely used where excellent corrosion resistance and moderate strength are required.
What is the difference between Grade 1 and Grade 2 titanium? Both are commercially pure titanium. Grade 1 generally provides greater ductility and lower strength, while Grade 2 provides higher strength with excellent corrosion resistance.
What is Grade 5 titanium? Grade 5 is Ti-6Al-4V, an alpha-beta titanium alloy widely used where high strength and a high strength-to-weight ratio are important.
Which titanium grade is best for aerospace? Grade 5 is a common aerospace choice. Grade 9 and Grade 23 are also used for specific aerospace applications where their particular property combinations are advantageous.
Which titanium grade is best for chemical processing? Grade 2 is commonly used for many chemical-processing applications. Grade 7 and Grade 12 can be considered when additional resistance to specific corrosive conditions is required.
Which titanium grade is best for seawater? Titanium has excellent resistance to seawater. Grade 2 is a common selection for marine service when the additional strength of an alloy is not required.
Which titanium grade is easiest to form? Commercially pure titanium grades generally provide better formability than high-strength alpha-beta alloys such as Grade 5.
Which titanium grade has the highest strength? High-strength titanium alloys can substantially exceed the strength of commercially pure grades. Grade 5 is one of the most widely used high-strength titanium alloys.
What is Grade 23 titanium? Grade 23 is Ti-6Al-4V ELI, an extra-low-interstitial version of the Grade 5 alloy with improved ductility and fracture toughness characteristics.
Can titanium be welded? Many titanium grades can be welded successfully, but titanium requires strict control of shielding and contamination because oxygen and nitrogen pickup can adversely affect properties.
Can this selector guarantee the correct titanium grade? No. It is a preliminary selection aid. Final selection must be checked against the applicable ASTM, ASME, AMS or other required specification and the actual service conditions.
