Description
Titanium Grade 9 Rod ASTM B348 is an alpha-beta titanium alloy
composed of titanium, aluminum, and vanadium. It offers excellent
corrosion resistance, high strength-to-weight ratio, and superior
weldability. This alloy is stronger than commercially pure titanium
and is widely used in aerospace, medical, chemical, marine, and
automotive applications.
Grade 9 titanium rods can be machined using appropriate coolant and
high-speed tungsten carbide or cobalt-based tools. They can also be
hot or cold formed using hydraulic presses, power brakes, stretch
forming, or drop hammer techniques.
