Strip Titanium Grade 9 Ti-3-2.5

Strip Titanium Grade 9 Ti-3-2.5

Titanium Grade 9 / Ti-3-2.5

UNS R56320
W.Nr 3.7194

Description

Titanium Grade 9 is a near alpha, alpha-beta alloy. It offers much more strength than CP titanium, and unlike Ti-6-4 can be cold worked resulting in moderately high strength and good ductility. It is as weldable as the CP grades and has excellent resistance to corrosion.

Industries Supplied

Architecture, medical, marine, processing & chlorate manufacturing, dimensional stable anodes, and desalination.

Additional Information on Grade 9 Titanium

Grade 9 Titanium is another titanium alloy that is very useful in a variety of different industries. Just like all of its counterparts, you can rely on the alloy to be resistant to corrosion, the ability to be cold worked, and have a high level of weldability. When you examine its strength, you will see that it lies somewhere between Grade 4 and Grade 5 although unlike those alloys, Grade 9 contains trace amounts of aluminum and vanadium. Furthermore, it can be used in higher temperatures than the titanium alloy Grades 1-4.

One thing that you will see with Titanium Grade 9 is that it also is very ductile, and is perfect to make tubing for hydraulics. In fact, the aerospace industry uses it for their airplanes quite regularly. Grade 9 Titanium tubing can withstand hot and cold temperatures, which means that it works well with hydraulics that have been sitting in extremely cold temperatures, or ones that have been moving rigorously and have heated up. This is why it is perfect for airplanes, which have a lot of moving parts at times, and glide through the air in the very cold atmosphere in others.

The medical and chemical processing industries also use Titanium Grade 9 (2-3.5) on occasion for their equipment and machinery. Often times in chemical processing you will find that it is used where the chlorate is present. In fact, you can even find the alloy in varying pieces of athletic equipment. This goes to show how extremely versatile the alloy is, and how it can be used in a variety of different ways. Also, just like the other grades of titanium, due to its amazing corrosion resistance, you will see Grade 9 Titanium in boats and other pieces of equipment that have to be operated in sea water, where corrosion can happen in an instant.
