What is a GR12 titanium tube?
Titanium Grade 12 is lightly alloyed near-alpha alloy with the chemical component of Ti-0.3Mo-0.8Ni. The alloy contains elements of Mo and Ni, which offers Titanium Grade 12 with superior corrosion resistance and increased strength while maintaining other excellent properties as pure titanium grades. The superior corrosion resistance can resist the attack from highly oxidizing and mildly reducing environments. In addition, Grade 12 has excellent crevice corrosion resistance (especially in chloride-containing media), good heat and wear resistance and is highly weldable. Grade 12 can be hot or cold formed using press brake forming, hydropress forming, stretch forming or drop hammer method. Like other low-alloy titanium materials, Titanium Grade 12 is mainly developed for use in the chemical industry.

Fabrication with Titanium Alloy
Titanium alloy grade 12 is forged conventionally, within the narrow temperature range 815 – 900°C. Titanium and titanium alloys are generally more difficult to forge than both aluminium and alloy steels, due to their high strain rate sensitivity and rapid increase of strength with falling temperature. Hot forging leaves a thick, hard outer layer of titanium oxide on the surface. This layer is called "Alpha Case" and is usually removed by pickling in a mixture of nitric and hydrofluoric acids. As supplied, titanium alloys are usually annealed and pickled, and can be readily cold formed in conventional machines using standard methods. In cold forming the "alpha case" does not form and further pickling is not needed, except to remove any carbon steel embedded in the surface, which can cause pitting corrosion.
