ASTM B861/B862 GR.7 Seamless / Welded tube Corrosion Resistance:
Titanium has strong corrosion resistance in many media, especially in neutral and oxidizing media, and can also be used in some dilute reducing acids, such as various concentration of nitric acid. It has good corrosion resistance to most alkaline solutions, such as saturated solutions of barium hydroxide, calcium hydroxide and magnesium hydroxide at room temperature, but it cannot be used in boiling sodium hydroxide solutions. Titanium is not corroded at all in seawater, and it is also very resistant to most organic acids (except formic acid, oxalic acid). It has excellent corrosion resistance in wet chlorine gas and chloride solutions such as chlorite and hypochlorite. The corrosion resistance in sodium chloride solution increases with the increase of the pH value of the solution
