Titanium and titanium alloy is a silver-white metal, low density, and has the advantages of high temperature resistance, low temperature resistance, corrosion resistance, light weight and so on. Density: 4.51g/cm3, titanium and oxygen elements have a good affinity, can form a dense oxide film on the surface of the titanium matrix, so as to protect the matrix from corrosion, and titanium products are acid resistant, alkali resistant environment, and have good mechanical properties, is a high-strength metal material.
1. One of titanium products – titanium plate
Titanium plate is a product made of titanium sponge, which can make titanium rods, titanium plates, titanium tubes, titanium forgings, titanium fasteners, titanium tableware and so on. There are many types of titanium plates, pure titanium, titanium alloy, because of the differences in chemical elements, so their performance, and use are not the same.
2. Production process of titanium plate
- Hot forging: Titanium metal has been forged at recrystallization temperatures to increase mechanical properties through mechanical stress.
- Hot rolled titanium plate: titanium metal is rolled above the recrystallization temperature, through the compression deformation of the roller, hot rolling can change the performance, by changing the organizational properties, improve the process performance.
- Cold rolled titanium plate: rolling process where the plastic deformation temperature is lower than the return temperature. Hot rolling and cold rolling can be based on the thickness of the titanium plate, usually hot rolling with a higher thickness, and cold rolling is generally used for small thickness, such as: 0.5mm-1.2mm titanium plate, AMS4911 ultra-thin aerospace titanium plate, all of which use cold rolling processing technology.
- Titanium plate annealing: titanium plate annealing is an important processing process, the titanium plate processing to the specified temperature, the specific temperature can be different according to the different standards, and then according to a certain temperature cooling of a titanium heat treatment process.
- Titanium plate pickling: Pickling refers to the removal of metal oxides on the surface of titanium plates through an acidic solution.
