Properties and Application of Titanium Plate and Titanium Alloy Plate


Titanium is an inert metal. Its chemical symbol is ti. Its atomic number is 22. It is a silver metal. Its specific gravity is 4.5, and its melting point is 1668 C. It is abundant in the crust, second only to iron, aluminium and magnesium, ranking fourth, more than ten times more than the sum of copper, nickel, lead and zinc commonly used. The ores used to produce titanium in industry are rutile, ilmenite and ilmenite. Due to the difficulty of separation and extraction, industrial titanium was not produced until the 1940s. Therefore, titanium is generally called rare light metal.

Because different products in different fields need different titanium and titanium alloy products, people can process them into sheets, rods, tubes, ribbons, wires and other shapes which can be deep processed to meet the needs of different fields, among which titanium plate, titanium bar and titanium tube are the most widely used. The following is an introduction to the properties of titanium plates commonly used in chemical industry:

I. Implementation Standards for Titanium Plates and Titanium Alloy Plates: GB/T3621-2007

II. Titanium Plate and Titanium Alloy Plate Product Brand, State and Specification

IV. Surface Quality

The surface of titanium plate should be smooth and metallic. Sheets are allowed to be delivered on sandblasted surfaces.

Slight darkening and local water marks are allowed on the surface of the titanium plate; local defects are allowed, such as scratches, indentations and pits, which do not exceed half of the thickness tolerance, but the minimum thickness should be guaranteed.

The surface of titanium plate is not allowed to have macro defects such as cracks, peeling, oxide peeling, crushing, metal and non-metal inclusions and marks of alkali washing.

Titanium plate is allowed to clear local defects along rolling direction, but the thickness of the plate after removal is not less than the minimum allowable thickness.

In addition, the titanium plate should not be stratified.

V. Application of Titanium Plate

Titanium and titanium alloys have low density and high tensile strength. In the range of - 253 - 600 degrees Celsius, their specific strength is almost the highest in metal materials. They can form a thin and hard oxide film in an appropriate oxidizing environment with excellent corrosion resistance. In addition, it has the characteristics of non-magnetic and low linear expansion coefficient. This makes titanium and alloys first known as important aerospace structural materials, and then extended to shipbuilding, chemical industry and other fields, and has been rapidly developed. Especially in the chemical industry, more and more products are used titanium and titanium alloy products, such as petrochemical industry, fiber, pulp, chemical fertilizer, electrochemistry and seawater desalination industries, as exchangers, reaction towers, synthesizers, autoclaves and so on. Among them, titanium plate is used as electrolytic plate, electrolyzer, reactor body and reactor body in electrolysis and sewage desalination.

With the development of science and technology, the application fields of titanium materials are more and more extensive, such as medical treatment, automobile, sports and so on. Through these, titanium as a light metal has been truly reflected. Its excellent characteristics are more and more recognized and determined by people, and it is integrated into me as soon as possible to replace other metals. We produce applications, even in our bodies.
