Neeka Tubes is a leading manufacturer and supplier of Titanium Gr.2 Fasteners worldwide. We offer various types of fasteners including bolts, nuts, studs, threaded rods, screws, washers and more that are made from pure titanium known for excellent corrosion resistance, lightweight properties and high strength. Titanium Grade 2 Fasteners are ideal for various industrial applications due to their superior performance in challenging environments.
Ti alloy Grade 2 fasteners are composed primarily of titanium (99.2% min) with additions of carbon (0.1% max), iron (0.3% max), oxygen (0.25% max), nitrogen (0.03% max) and hydrogen (0.015% max). These fasteners exhibit excellent mechanical properties with a yield strength of 275 MPa and tensile strength of 344 MPa. Our titanium grade 2 bolts & nuts are available in lengths ranging from 3 mm to 200 mm and sizes from M10 to M36. We manufacture them in square, hex, threaded rods and round form and comply with IS, BS and ASTM standards.
Features of Titanium Gr.2 Fasteners
Titanium Gr.2 Fasteners are used in chemical, marine, aerospace and medical sectors. They are particularly suitable for applications like wastewater recovery systems, ClOβ generators, hydrocarbon processing, marine engines and other chemical processes due to their exceptional corrosion resistance, lightweight nature and durability in extreme conditions.
