Titanium Grade 5 Fasteners Manufacturer and Supplier in India
Titanium Grade 5 (Ti-6Al-4V, UNS R56400) fasteners deliver roughly 2.5 times the yield strength of commercially pure titanium while retaining a strength-to-weight ratio far above steel, making them the standard choice for aerospace, high-performance automotive and marine fastening applications manufactured to ASTM F2281 and ASME B18.2.1.They are known as UNS R56400 and Werkstoff 3.7165 and have a minimum tensile strength of 950 MPa and yield strength of 880 MPa and a density of about 4.43 g/cm 3. They are strong and light which will help minimize assembly weight and maximize joint performance! The alloy is also coated with a stable titanium oxide film, which helps to prevent pit and crevice corrosion, as well as from chlorides and environments. Sachin Steel Centre is a prominent manufacturer and supplier of Titanium Grade 5 Bolts, Nuts, Screws, Studs and Threaded Fasteners in India with precision manufacturing ability to provide for highly demanding industrial applications.

Frequently Asked Questions

Titanium Grade 5 Fasteners are Ti-6Al-4V titanium alloy bolts, nuts, screws, studs, and other fasteners known for high strength, low weight, and corrosion resistance.
Yes. They offer excellent corrosion resistance in seawater, chlorides, oxidizing environments, and many industrial conditions due to their protective titanium oxide film.
Grade 5 offers roughly 2.5x the yield strength of Grade 2 (828 MPa vs ~345 MPa), so it is specified wherever higher clamp load or fatigue resistance is required, such as aerospace assemblies.
Yes, up to approximately 400°C, after which strength begins to fall off — for higher-temperature service other titanium or nickel alloys are typically specified.
AMS 4928 and AMS 4967 are the common aerospace bar/forging specifications for Ti-6Al-4V used in fastener manufacture.

Typically 6 mm to 200 mm diameter in mill, turned, or polished finish, supplied as bar stock or custom-cut lengths.

Titanium Grade 5 is primarily titanium alloyed with approximately 6% aluminum and 4% vanadium, with small amounts of other elements.
Yes, they can be used at elevated temperatures, but their allowable temperature depends on the application, load, exposure time, and design requirements.
Yes. Titanium Grade 5 is a heat-treatable alloy, and appropriate heat treatment can increase its strength and mechanical performance.
