Introduction to Titanium GR2 Fasteners

Titanium Grade 2 (Ti GR2) fasteners are lightweight yet durable, with a tensile strength sufficient for high-performance industrial applications, and they maintain their integrity at elevated temperatures up to approximately 400°C (750°F). Ti GR2 fasteners material is easily machinable with proper precautions, and it can be forged, hot-rolled, cold-rolled, stamped, bent, or drawn, allowing flexibility in manufacturing. Annealing between 1103°F and 1400°F followed by air cooling is performed to relieve stress and enhance ductility. Compared to Ti Grade 5, Ti GR2 fasteners are more cost-effective while still delivering excellent corrosion resistance and mechanical performance. They are suitable for environments where exposure to chlorine, saltwater, or other corrosive media is significant. Ti GR2 fasteners provide reliable performance, durability, and versatility, ensuring secure and long-lasting connections in critical applications.

Frequently Asked Questions About TI GR2 Fasteners

Ti Grade 5 bolts are strong, lightweight titanium alloy fasteners (Ti-6Al-4V) with excellent corrosion resistance and a high strength-to-weight ratio, suitable for aerospace, marine, automotive, and heavy-duty applications. They retain strength at temperatures up to 540°C.

Ti Grade 2 fasteners are lightweight, corrosion-resistant, and moderately strong. They offer flexibility for precision applications, durability in harsh environments, and are a cost-effective choice compared to alloyed titanium grades.

Yes, Ti GR2 fasteners are highly suitable for marine applications. They form a stable, protective oxide layer that prevents corrosion even in seawater and chloride-rich environments. This makes them ideal for offshore platforms, shipbuilding, desalination plants, and other saltwater-exposed equipment.

Yes, Ti GR2 fasteners can withstand elevated temperatures up to around 400°C (750°F) without losing mechanical integrity. This makes them suitable for use in industrial equipment, heat exchangers, and piping systems that operate under high-temperature conditions.

Titanium Grade 2 fasteners are available as bolts, nuts, screws, studs, and washers. They can be supplied in coarse or fine threads, forged or machined forms, and in standard or custom sizes, catering to a wide range of industrial, medical, and aerospace applications.
