Gr2 titanium flange have high strength and corrosion resistance . Titanium is an active element in the air can be produced with oxygen, in its surface to produce a layer of dense oxide film, titanium oxide has a strong hardness and corrosion resistance, blocking the titanium and other chemical elements Reaction, we produce titanium products, through a special pickling treatment, in a certain concentration of nitric acid and hydrofluoric acid mixed solution soaking, so that titanium surface smooth, and increase the thickness of titanium oxide film to ensure that gr2 titanium flange can have More excellent corrosion resistance.
