Titanium Grade 2 fasteners offer an impressive combination of moderate strength and exceptional ductility, making them suitable for both load-bearing and lightweight structural applications. With a tensile strength ranging between 345 MPa to 450 MPa, these fasteners strike a balance between durability and formability. This makes them an ideal choice for industries like aerospace, power generation, and chemical processing where strength is needed without adding unnecessary weight.
Another notable advantage of Titanium Grade 2 is its excellent performance across a wide range of temperatures. These fasteners maintain their mechanical integrity even at cryogenic temperatures and can withstand elevated temperatures up to approximately 400°C (752°F) without significant loss of strength. This thermal stability makes them suitable for applications exposed to fluctuating or extreme heat conditions, such as heat exchangers, condensers, and desalination plants.
In terms of fabricability, Grade 2 titanium is among the easiest of all titanium grades to machine, form, and weld. It exhibits superior weldability using conventional welding techniques such as TIG or MIG welding, without requiring preheat or post-weld heat treatments. Its cold formability also ensures ease of manufacturing for custom bolt types or configurations, allowing engineers flexibility during design and installation.
