Titanium Grade 5 Specification

Titanium Grade 5 has good tensile properties at ambient temperature and a useful creep resistance up to 300^oC (570^oF). 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.
