Titanium Design

For the oil tool designer, consideration must be given to titanium’s unique characteristics:

• High Temperature Mechanical Properties
• Superior Corrosion Resistance
• Low Density
• Low Modulus
• Low Thermal Expansion
• Non-Magnetic Permeability
• Low Wear Resistance 

Titanium Cost

An important point is that when considering cost, initial material cost is only one of many factors associated with overall system or project cost.  Other factors include: improved productivity resulting in increased performance, avoidance of potential maintenance and downtime costs, energy and equipment savings resulting from high strength and light weight materials, system life-cycle replacement costs.  Not surprisingly, when “total system cost” is calculated, the initial material investment made with titanium is minimized over the life of the system. 

Titanium Grades

Below is an overview of the several titanium alloys and grades which Titanium Engineers utilizes to build machined components, including Titanium Grade 2, Titanium Grade 5,  Titanium 6-2-4-6 and Titanium Grade 19, more commonly known as Titanium Beta-C.

Titanium Grade 2
Titanium Grade 2 is an unalloyed titanium and what is considered a "commercially pure" titanium. Titanium Grade 2 is used commonly in applications that require welding because of its strong weldability properties. Titanium Grade 2 is light weight and highly corrosion resistant, but has much lower strength than alpha-beta or beta titanium alloys. Titanium Engineers produces titanium bar, seamless tube and titanium machined components in Titanium Grade 2.

Titanium Grade 5
Titanium Grade 5 is the most commonly used Titanium worldwide and is the most commonly used alloy in the oilfield. Titanium Grade 5 is an alloyed titanium and is considered to be an alpha-beta alloy. Titanium Grade 5 is alloyed with 6% Aluminum and 4% Vanadium and is commonly known as Ti 6Al -4V. Titanium Engineers produces titanium bar, seamless tube and titanium machined components in Titanium Grade 5.

Titanium 6-2-4-6

Titanium 6246 is used in high strength applications, applications requiring materials that meet NACE MR0175/ISO 15156 and applications requiring more strength than TI Gr. 5 (6Al-4V).  Titanium 6246 is an alpha-beta alloy.  It has better response than Ti Gr. 5 when heat treating to high strength levels.  Titanium Engineers provides Ti 6246 in titanium bar or titanium tube form, or as machined components.

Titanium Beta-C (Titanium Grade 19)
Titanium Beta-C, or Ti Beta-C, is used in high strength applications, applications requiring materials that meet NACE MR0175/ISO 15156 and applications requiring more strength than TI Gr. 5 (6Al-4V)or Ti 6246. Titanium Beta-C is a Beta alloy; Beta alloys are the smallest group of titanium alloys and have good hardenability and can be heat treated to high yield strengths. Titanium Engineers produces titanium bar, seamless tube and titanium machined components in Titanium Grade 19 or Titanium Beta-C.
