Grades of Titanium Materials

Grades of Titanium Materials

Titanium materials are widely used now, and everyone is not very clear about this brand conversion, so I will share Grades of Titanium Materials with you today.

Grade 1 Titanium:
The most ductile and softest titanium alloy. It is a good solution for cold forming and corrosive environments.

Grade 2 Titanium:
Unalloyed titanium, standard oxygen.

Grade 3 Titanium:
Unalloyed titanium, medium oxygen.

Grades 1-4 are unalloyed and considered commercially pure or “CP”. Generally the tensile and yield strength goes up with grade number for these “pure” grades.The difference in their physical properties is primarily due to the quantity of interstitial elements. They are used for corrosion resistance applications where cost, ease of fabrication, and welding are important.

GRADE Carbon Nitrogen Oxygen Hydrogen Iron Titanium Tensile Yield Elong. ( 2″)
Max % Max % Max % Max % Max %   KSI KSI %
1 0.08 0.03 0.18 0.015 0.2 Balance 35 25 24
2 0.08 0.03 0.25 0.015 0.3 Balance 50 40 20
3 0.08 0.05 0.35 0.015 0.5 Balance 65 55 18
4 0.08 0.05 0.4 0.015 Balance 80 70 15

Grade 5 Titanium:
Also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4
Applications: Blades, discs, rings, airframes, fasteners, components. Vessels, cases, hubs, forgings, Biomedical implants.

Ti-6Al-4V standard specifications include:
AMS: 4911, 4928, 4965, 4967, 6930, 6931, T-9046, T9047
ASTM: B265, B348, F1472
MIL: T9046 T9047
DMS: 1592, 1570

Grade 7 Titanium:
Contains 0.12 to 0.25% palladium. This grade is similar to Grade 2. The small quantity of palladium added gives it enhanced crevice corrosion resistance at low temperatures and high pH.

Grade 9 Titanium:
contains 3.0% aluminium and 2.5% vanadium. This grade is a compromise between the ease of welding and manufacturing of the “pure” grades and the high strength of Grade 5. It is commonly used in aircraft tubing for hydraulics and in athletic equipment.

Grade 12 Titanium:
contains 0.3% molybdenum and 0.8% nickel.

Grade 23 Titanium:
Also known as Ti-6Al-4V-ELI or TAV-ELI, contains 6% aluminium, 4% vanadium, 0.13% (maximum) Oxygen.ELI stands for Extra Low Interstitial. Reduced interstitial elements oxygen and iron improve ductility and fracture toughness with some reduction in strength.[TAV-ELI is the most commonly used medical implant-grade titanium alloy.

Ti-6Al-4V-ELI standard specifications include:
AMS: 4907, 4930, 6932, T9046, T9047
ASTM: B265, B348, F136
MIL: T9046 T9047
