What is a GR12 titanium tube?
Designated as UNS R53400, titanium grade 12 has the nominal composition of Ti-0.3Mo-0.8Ni. It's a titanium alloy that may be treated as unalloyed titanium (commercially pure titanium) with minor traces of alloying contents. Compared to commercially pure titanium (grade 1, 2, 3, etc), the nickel and molybdenum alloying contents result in improved strength and better corrosion resistance. Although its corrosion resistance is not as good as grade 7 titanium (titanium-palladium alloy), grade 12 titanium is much more cost-effective. Generally, titanium grade 12 materials are furnished in annealed condition. It is particularly resistant to crevice corrosion in hot brine, however, cautions must be taken when it is used for solutions with pH value less than 3. The microstructure of grade 12 titanium is near α phase, which is either equiaxed or acicular alpha with minor amount of beta.
