titanium alloy plate

Samples for chemical analysis shall be representative of the material being tested. The utmost care must be used in sampling titanium for chemical analysis because of its great affinity for elements such as oxygen, nitrogen, and hydrogen.
Therefore, in cutting samples for analysis, the operation shouldbe carried out insofar as possible in a dust-free atmosphere.
Chips should be collected from clean metal and tools should be clean and sharp. Samples for analysis should be stored insuitable containers

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 nitric acid of various concentrations from room temperature to boiling point. 
It has good corrosiveness to most alkali solutions, such as barium hydroxide, calcium hydroxide and magnesium hydroxide saturated solution at room temperature, but can not be used in boiling sodium hydroxide solution.
 Titanium is not corroded at all in seawater, and it is also resistant to corrosion in most organic acids. It has excellent corrosion resistance in nitride solutions such as wet chlorine and hypochlorite. The corrosion resistance in sodium chloride solution increases with the increase of PH of the solution.
