Titanium And Titanium Alloy Plates In Chemical Industry

Titanium is an inert metal, its chemical symbol is ti, atomic number is 22 and its a silver metal. The specific gravity is 4.51, the melting point is 1668℃. Because different products in different fields require different titanium and titanium alloy products, people process them into plates, bars, pipes, tapes, wires and other shapes that can be further processed for the majority of demanders to meet the requirements of different fields. Among these, titanium rings and titanium forgings are the mostly widely used. The following are the specifications and performance of commonly used titanium plate in chemical industry.

4、Surface Quality

The surface of titanium plate should be smooth and clean with metal nature color. Plates are allowed to be delivered with a sandblasted surface. Slight dimming/darkening and partial water marks are allowed on the surface; Partial defects, scratches, indentation, pits and other defects without exceeding half of the thickness tolerance are allowed, but the minimum thickness shall be guaranteed. The surface is not allowed to have cracks, peeling, oxide scaling, folding, metal and non-metal inclusions and other macroscopic defects and alkali washing traces. Titanium plate is allowed to clear the partial defects along the rolling direction, but the thickness of the plate after removal is not less than the minimum thickness. In addition, titanium plate should not be layered.
