Titanium Beta-C is a metastable beta alloy which can be heat treated to high strength levels. The alloy contains beta stabilizer elements which allow it to retain the high strength beta phase after quenching. It can be solution treated and aged to provide increases in strength above convention alpha and beta titanium alloys. Because it has one of the lowest densities for a beta titanium alloy, it has a very high specific strength (strength/density).

As in other titanium alloys, Beta-C titanium alloy has a high level of corrosion resistance based on the existence of a consistent and continuous oxide layer which is formed spontaneously upon exposure to oxygen. In addition, due to its approximate 4% molybdenum content, Beta-C titanium alloy has excellent resistance to corrosion in reducing environments such as Hydrogen Sulfide (H2S). It has excellent resistance to corrosion in seawater making it a good choice for use in offshore and subsea oil & gas operations where corrosion, strength, and weight are concerns.

Beta-C titanium, like other titanium alloys, has a modulus of elasticity of 107 Gpa (15.5 x 103ksi), roughly half that of alloy steels. It also has excellent fatigue resistance, therefore it can be beneficial when used in component designs that will need to elastically deform repeatedly under high stresses. Another benefit of Beta-C titanium is its ability to retain relatively high levels of strength at temperatures up to 350°C.

Applications
Titanium Beta-C can be used in applications where very high strength, light weight and corrosion resistance are important. It has been used in a variety of applications involving oil & gas drilling, well completion and intervention, and hydrocarbon production where traditional alloys do not have sufficient strength at higher temperatures, or do not conform to the NACE MR0175 / ISO 15156 standard for severe service.

Because of the low modulus of elasticity, Titanium Beta-C has also been used for housings and shafts in high pressure/high temperature (HPHT) environments.

Titanium Beta-C has also been used in high-performance motorsport applications where high strength-to-weight ratio and the low modulus of elasticity are important factors.
