Titanium Grade 5 has good tensile properties at ambient temperature and a useful creep resistance up to 300oC (570oF). Resistance to fatigue and crack propagation is excellent. Like most titanium alloys, Grade 5 has outstanding resistance to corrosion in most natural and many industrial process environments.
Titanium Grade 5 is also known as Titan Grade 5 and Allvac 6-4.
