Titanium Grades & Tube Supplier

Ti-Fab commonly stocks and supplies the following Titanium Grades. The grades have different applications and benefits, which we go into greater detail below. If you have any questions, please contact Ti-Fab today! 

Titanium Grade 2

Titanium grade two is extremely versatile and can be used in a variety of applications and industries. 

Titanium Grade 2 Shapes in Stock:

• Plate
• Sheet
• Pipe
• Fitting
• Bar & Billet
• Tubing

 Titanium Grade 2 Common Industries:

• Architecture
• Medical Industry
• Chemical Processing
• Desalinating
• Architecture

 Titanium Grade 5 

Titanium Gr.5 is very common in the defense and aerospace industry due to its higher strength properties.  One of its added benefits is that it can be heat-treated to increase its strength. It is excellent in seawater environments with agitators and pump impellers. 

Titanium Grade 5 Shapes in Stock:

• Plate

• Sheet

• Bar & Billet

Titanium Grade 5 Common Industries: 

• Rotating equipment

• Naval Components

• Aerospace Components

• Engine Components

• Marine Industry

Titanium Grade 7

Titanium Grade seven is the most corrosion-resistant of all titanium alloys. It is equivalent to Grade 2, however, it has palladium added for the most severe environments. It is commonly stocked in plates, sheets, pipes, fittings, and tubing. 

 Titanium Grade 7 Common Industries:

• Chemical Processing

• Hydrocarbon Processing

Titanium Grade 12

Titanium Gr.12 was first produced for seawater use to replace copper nickel tubing in heat exchangers. It is very weldable making it extremely versatile. It offers a lot of strength even at high temperatures. We offer this grade in plate and tubing. 

 Titanium Grade 12 Common Industries:

• Marine Industry
• Aircraft components
• Heat exchangers
• Chemical Manufacturing

Titanium Grade 16

Titanium Gr.16 is a “lean palladium” option that offers similar corrosion resistance to titanium grade 7 at a reduced cost due to less palladium alloy included. This is not as common grade so it’s not as readily available, but TiFab does stock this grade in tubing in various sizes.

 Titanium Grade 16 Common Industries:

• Hydrocarbon Processing
• Chemical Processing

Guide to Common Industrial Titanium Grades

Standard and Precious Metal Enhanced Titanium Alloys

Titanium Mechanical Properties (ASTM plate specification, minimum)

*    Unalloyed grades are also referred to as Commercially Pure or CP.

**  Grades listed in parenthesis are mechanically identical but contain small amounts of palladium or ruthenium for enhanced corrosion resistance. 

***  The fatigue values in the table are estimated based on 50% of the ultimate strength for tension to tension loading cycles and do not take in to account environmental effects which may reduce the acceptable values. Welds and cast material will exhibit lower values.  Weld metal values are estimated as 80% of the base metal values.  In addition, a reduction for notch effects and stress raisers may be needed, depending on design details utilized. The values do not include any safety factor or design margin of safety and should usually be de-rated by a factor of from 1.5 to 4, depending on design accuracy, service conditions, inspection, cost of maintenance, and severity of a failure.

Endurance or fatigue limit values at room temperature in air are estimated based on tensile strength and generally apply to 0 to limit stress load cycles.  Values may be different for different loading cycles.  Values are reduced for weld metal and castings, and may be reduced in some environments, and must always account for notch effects and stress raisers.
