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. We stock this grade in the following shapes: 

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

 

The wide range of shapes and versatility of titanium grade two makes it a great choice for a variety of application including: 

  • 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.  We stock this grade in the following shapes:

  • Plate
  • Sheet
  • Bar & Billet

 

Some of the most common industries that use Titanium Grade 5 include: 

  • Rotating equipment
  • Naval Components
  • Aerospace Components
  • Engine Components
  • Marine Industry

 

Titanium Grade 7

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

 

Common industries that use titanium alloy grade 7 are: 

  • 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. Some of the common applications include of Titanium Grade 12: 

  • 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 as 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.  It is corrosion-resistant and used in a variety of industries, including: 

  • Hydrocarbon Processing
  • Chemical Processing

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.
