Titanium Grade 12 Uses
This grade of titanium is great in high-temperature applications. With excellent high-quality weldability, Titanium Grade 12 retains it's strength.
It can be hot- and cold formed, and with characteristics similar to 300 series stainless steels, it is ideal for the following industries:
Heat exchangers
Marine and airfare components
Elevated temperature chemical manufacturing
Hydro-metallurgical applications
