ASTM F468 Grade 5 Titanium Hex head Bolts, Titanium Grade 5 Hex bolt,stud bolt
ASTM F468 UNS R56400 represents grade specification for Titanium Grade 5 Bolts, Screw Fasteners. It covers both coarse and fine threaded Ti Alloy 5 Bolts, screws, stud bolts. Below is the chemical, mechanical and other requirements. ASTM F468 UNS R56400 Fasteners carry EN 10204 Type 3.1 Certification.
The grade 5 Titanium alloy is considered to be the workhorse among the titanium alloy industries. It is a fully heat treatable alloy and can be quickly welded to form parts for aerospace machines, as well as marine and offshore applications. It is one of the critical components for engine parts of many vessels.
When compared to pure commercial Titanium, this is found to be stiffer and has the same thermal properties. It also has excellent fatigue resistance and low thermal expansion capability, making it suitable for subsea gas and oil industries.
grade 5 (Ti-6Al-4V) titanium which is the most widely used titanium alloy.
Common Names:
- Ti6Al4V
- Ti-6Al-4V
- Ti 6-4

A Tensile stress areas are computed using the following formula: As = 0.7854 [D- (0.9743/n)]2
Where:
As = Tensile stress area, in.2,
D = Nominal size (basic major diameter), in., and,
n = number of threads per inch.
