Titanium Screws, Fasteners and Fixings

Titanium is a favoured material for a fastener due to the attractive property of being a low-density metal, however, its elastic modulus is another property that makes it such an appreciated metal for internally and externally threaded fasteners.

They are used relatively heavily within the automotive, aeronautical and aerospace industries for when titanium’s advantages outweigh the choice of a steel fastener.

It has higher tensile strength than many other materials, even in higher temperatures, whilst also being extremely resistant to seawater – which makes it ideal for naval applications as well.

The pairing of their high strength to weight ratio, excellent resistance to stress corrosion cracking, high corrosion resistance and good fatigue strength make them useful in a huge number of industries.

Titanium Fasteners host unparalleled resistance to chloride solutions, hypochlorides, chloraes, perchlorates, sodium chlorite and chlorine dioxide. Chlorides like those listed above are common in seawater and pulp and paper applications and are a menace to the inudstry. However, Titanium cannot be used with dry chlorides or it will rapidly corrode.

There are a number of grades of titanium, much like stainless steel, including:

Grade 1, which is a commercially pure titanium grade and the softest and most ductile of the grades, and hosts the best formability as well as excellent corrosion resistance. It is commonly available as titanium plate and tubing. Applications include chemical processing, chlorate manufacturing, architecture, automotive parts and much more.

Grade 2 titanium is considered the workhorse of the titanium industry and shares many of the qualities that Grade 1 has. Applications for Grade 2 include power generation, exhaust pipe shrouds, desalination and airframe skins.

Grade 3 is stronger than 1 and 2, as well as being similar in ductility and slightly less formable, and can be found in aerospace structures, the medical industry and marine industry.

Grade 4 is known as the strongest of the above and is known for excellent resistance to corrosion, good formability and good weldability. It can be found in cryogenic vessels, condenser tubing, pickling baskets and more.

There’s also a number of alloy grades, including Grade 7 which is an equivalent to Grade 2, and often found in chemical processes and production equipment components.

Other alloy grades include grade 11, grade 5, grade 12, and grade 23.
