Grade 5 titanium has good tensile strength properties at room temperature and useful creep resistance up to 300 ° C. Resistance to fatigue and crack propagation is excellent. Like most titanium alloys, Grade 5 has exceptional corrosion resistance in most natural environments and many industrial process environments.
The ability to age this alloy makes it a good choice for applications such as springs and fasteners.
APPLICATIONS
Grade 5 titanium is pure alpha-beta titanium with aluminum as an alpha stabilizer and vanadium as a beta stabilizer. This alloy is primarily used for corrosion resistance and is the most widely used specification in all product forms. The alloy is characterized by very high strength, good corrosion resistance, excellent strength / weight ratio and high resistance to cryogenic temperatures.
Weldability Grade 5 alloy is easily welded in the annealed condition, or in solution and partially aged, with aging being completed during post weld heat treatment. Precautions must be taken to avoid contamination by oxygen, nitrogen and hydrogen. Fusion welding can be carried out in chambers filled with inert gas, or by using inert gas welding of the molten metal and adjacent heated areas with the aid of a towing shield.
Spot, seam and flash welding can be performed without resorting to protective atmospheres.
