ASTM B338 Grade 12 Ti 0.3 Mo 0.8 Ni (UNS R53400)

What is a GR12 titanium tube?

Titanium mixed with other chemical elements such as molybdenum, aluminum, nickel, and zirconium produces a wide range of titanium alloys.

Grade 12 Ti 0.3 Mo 0.8 Ni is a commercially pure wrought alloy. This alloy has excellent strength at high temperatures coupled with excellent weldability and crevice corrosion resistance.
