Titanium fasteners are becoming more and more important in the manufacture and assembly of products that have high-performance standards. As a result, it is incredibly important to know the different grades when it comes to titanium. Let’s take a look at some of the different grades of titanium fasteners
Grade 2 Titanium
This is one of the most common types of titanium and is the most used in the fastener industry. It is also the purest form of it, containing 99% titanium. Grade 2 titanium is idea for situations where you need very good corrosion resistance such as in environments with a lot of salt water and brine. They are also extremely resistant to other chemicals including chlorides.
Grade 5 Titanium
Grade 5 titanium has been modified to give it extra strength. It contains 90% titanium with the rest of it being made up of 4% vanadium and 6% aluminum. It has twice the strength and half the weight of comparable steel fasteners and maintains the corrosion properties of Grade 2 titanium.
Grade 7 Titanium
While grade 7 titanium isn’t used as often as grade 2 or 5, it’s still quite common in the fastening industry since it has increased resistance against corrosion.
Grade 23 Titanium
Grade 23 titanium has been created with improved mechanical properties even at cryogenic temperatures, making it less likely to suffer from fatigue and to crack.
