Grade 2 titanium has a varied usability and a wide availability, leading many manufacturers of titanium to use this material. It has many of the same quality of Grade 1 titanium but it is slightly stronger. It has the same corrosion resistance.

Grade 2 titanium possesses strength, good weldability, ductility and formability.

Titanium 6Al-4V Grade 5 UNS R56400

Ti 6Al-4V titanium is used the most of all alpha-beta titanium alloys. It is usually used in the annealed condition, at service temperatures up to 750°F. However it can be heat treated to gain high strength under 4″ thick. Hardenability is limited in sizes over 1″ and may not develop full properties. Ti 6Al-4V can be welded with matching or with an ELI filler wire.

Ti 6Al-4V is generally resistant to corrosion even though it still may be quickly attacked by environments that cause breakdown of the protective oxide. These include hydrofluoric (HF), hydrochloric (HCl), sulfuric and phosphoric acids. Inhibitors are know to reduce this for all but hydrofluoric. Ti 6Al-4V resists attack by pure hydrocarbons, and most chlorinated and fluorinated hydrocarbons.

Ti 6Al-4V can have chloride stress corrosion cracking (known as SCC) in some conditions, although it is known to be among the better of the titanium alloys in this regard. Generally silver plated bolts are not used with Ti 6Al-4V as silver bonds easily with chlorine. Ti 6Al-4V is also susceptible to SCC in environments such as methyl alcohol, red fuming HNO₃, and N₂O₄. In the case of red fuming nitric acid, SCC is limited to environments containing less than 1.5% water, or more than 6% NO₂. Failure in N₂O₄ has occurred when oxygen and chlorides were present as impurities.

Ti 6Al-4V Eli is one of the most commonly used titanium alloy. Neither this or Ti-6Al has corrosion properties quite as good as CP titanium but both of these grades are corrosion resistant to be used in seawater and oxidizing acids.

6AL-4V ELI is certified to ASTM F136 and is generally known as implant grade 6-4 Titanium. It is well suited for implants and medical devices due its properties of biocompatibility, corrosion resistance, high strength and toughness.

The main difference between Ti-6Al-4V ELI (Grade 23) and Ti-6Al-4V (Grade 5) is that in ELI (Extra Low Interstitials) the maximum oxygen content is lowered to .13% which gives the material an improved toughness.

This material is low interstitial version of Ti-6Al-4V, for maximum toughness. This grade is normally used in the annealed condition.

Stress relief 900-1200°F 1 to 4 hours, air cool. Duplex anneal, bar and forgings: Solution anneal 50-100°F below the beta transus, hold 1 hour minimum, air cool. Then reheat within the range 1300-1400°F, hold 1 hour minimum, air cool. Stress – relief annealing is performed after welding.

Applications:

Aerospace, Chemical processing, cryogenics vessels, medical, orthopedic implants, dental implants, bone and joint replacement, dental root implants, surgical clips.

Titanium Ti-3Al-2.5V Grade 9 UNS R56320

Also known as 3-2.5 Ti, this grade provides exceptional corrosion resistance to many harsh elements, such as seawater environments, salts and oxidizing acids. Grade 9 alloy is known for its weldability and formability, whether it be hot or cold.  This grade is a compromise between the ease of welding and manufacturing of the “pure” grades and the high strength of Grade 5.

This material is available in two conditions, annealed and cold worked stress relieved. Annealed has a lower tensile strength than CWSR, but has better forming capabilities. CWSR is stronger, but does not form as well as annealed.

Ti03Al-2.5V is an ideal material for applications such as aircraft and hydraulic system tubing due to its extreme lightweight. Other uses are for the manufacturing of sports equipment (tennis rackets, bicycles and golf clubs).
