Titanium alloy 40 has a high specific strength, it is paramagnetic, wear-resistant. These advantages are particularly valuable in mechanical engineering, aviation, where important heat resistance, corrosion resistance, combined with the strength. This is also true in the shipbuilding, rocket, railway transport. Some specific structural properties of the alloy 40 are of great interest for the food and chemical industries.
Possible designation in reference literature SP-40.

High-strength titanium alloys are alloyed with aluminum and vanadium, and heat resistance is achieved doped molybdenum and aluminum. Most used titanium alloys containing both molybdenum, aluminum, vanadium. Such alloys have a particularly high strength and corrosion resistance. Aluminum is the principal alloying element, it is also important for the titanium alloys, both iron carbon. The second important component is considered molybdenum.
