Products Description
Titanium Grade 12 is a titanium alloy alloyed with Ni, Pd and Mo with excellent corrosion resistance and higher strength than Titanium Grade 2. Titanium Gr.12 offers excellent corrosion resistance to acids as well as very good resistance to crevice corrosion in hot brines. Due to the higher strength, Titanium Gr.12 can be used with a thinner wall thickness than Titanium Gr.2 or Titanium Gr.7 under the same conditions.
