Application and Introduction of Titanium in 316Ti Stainless Steel

Application and Introduction of Titanium in 316Ti Stainless Steel 316Ti stainless steel pipe latest national standard 06Cr18Ni14Mo2Ti. 316Ti stainless steel is based on 316 stainless steel added a small amount of titanium content, due to the implementation of different standards of 316Ti stainless steel is not the same, 316Ti stainless steel titanium content requirements are also different, China's Baosteel 316Ti stainless steel titanium content of about 0.41, and The titanium content of 316Ti stainless steel imported from Japan's Nippon Steel is about 0.56. Because the composition of the elements is not the same, the prices of domestic 316Ti and imported 316Ti are relatively different. Application and Introduction of Titanium in 316Ti Stainless Steel Titanium and its alloys have many excellent characteristics such as light weight, high strength, strong heat resistance, corrosion resistance, etc., and are known as “Future Metals”, and are promising new structural materials. Titanium and its alloys not only have very important applications in the aerospace and aerospace industries, but also have been widely used in many industrial sectors such as chemical engineering, petroleum, light industry, metallurgy, and power generation. Another important feature of titanium is its strong corrosion resistance. This is because titanium and its alloys have many advantages, such as light weight, high strength, high heat resistance, corrosion resistance, and so on. They are known as "future metals" and have New structural materials for the development of the future. Titanium and its alloys not only have very important applications in the aerospace and aerospace industries, but also have been widely used in many industrial sectors such as chemical engineering, petroleum, light industry, metallurgy, and power generation. Another significant feature of titanium is its high corrosion resistance, which is due to its exceptional affinity for oxygen, which creates a dense oxide film on its surface that protects titanium from corrosion by the medium. Titanium metal forms a passivating oxide film on the surface in most aqueous solutions. Therefore, titanium has good stability in acidic, basic, neutral salt aqueous solution and oxidizing medium, and has better corrosion resistance than existing stainless steel and other non-ferrous metals, and can even be comparable to platinum. However, if titanium oxide film can be continuously dissolved in a medium, titanium will be corroded in this medium. For example, titanium is hydrofluoric acid, concentrated or hot hydrochloric acid, sulfuric acid, and phosphoric acid. Since these solutions dissolve the titanium surface oxide film, titanium is corroded. If an oxidant or certain metal ions are added to these solutions, the titanium surface oxide film will be protected and the stability of titanium will increase. 1. Chemical Industry Titanium has good stability in all kinds of acid, alkali, and salt media, except for the above-mentioned four kinds of inorganic acids and highly corrosive aluminum chloride. Therefore, titanium is an excellent anti-corrosion material in the chemical industry and has been increasingly used. For example, the use of titanium anodes and titanium wet chlorine coolers in the chlor-alkali industry has received very good economic results and has been hailed as a major revolution in the chlor-alkali industry. 2. Petroleum Industry Titanium has very good stability among organic compounds except for five organic acids (formic acid, acetic acid, oxalic acid, trichloroacetic acid, and trifluoroacetic acid) at higher temperatures. Therefore, titanium is an excellent structural material in petroleum refining and petrochemicals and can be used to make various heat exchangers, reactors, high-pressure vessels, and distillation towers. 3. Metallurgical Industry Titanium is an active metal with good air-intake performance. It is an excellent degassing agent in the steelmaking industry. It can synthesize oxygen and nitrogen that precipitate during cooling of steel. Adding a small amount of titanium (<0.1%) to the steel makes the steel tough and resilient. Titanium is also an important alloying additive in steelmaking, aluminum refining and other industries. Titanium has superconductivity and is a common superconducting material. In addition, titanium has a good stability in acidic solutions containing metal ions, so titanium has a very wide range of applications in hydrometallurgical industries, such as electrolytic production of non-ferrous metals such as copper, nickel, cobalt, and manganese. 4. Fertilizer industry urea is an important chemical fertilizer. In the production process, urea, ammonia, ammonium carbamate, and their mixed liquids are highly corrosive under conditions of high temperature and high pressure. After using titanium to replace stainless steel, the service life of the equipment is greatly increased, and the overhaul time is greatly reduced. . Therefore, titanium is the main equipment used in urea production. 5. Seawater Desalination and Shipbuilding Industry Titanium is more resistant to seawater corrosion than all other metals. Titanium has exceptional stability in both stationary and high-speed seawater. Therefore, titanium is an ideal material for seawater desalination devices. The number of titanium applications in this field will increase. Titanium resistance to seawater and sea air is highly corrosive, and its strength and weight make it an ideal structural material for the shipbuilding industry. It has been widely used in many parts of various ships and deep water submarines. 6. Titanium in the power industry has good stability in many corrosive hot waters such as chlorides and sulfides. Therefore, titanium has been widely used as a heat exchanger cooling pipe in thermal power plants. After replacing the copper-nickel alloy tube with a thin-walled titanium tube, not only the service life is greatly improved, but also the maintenance time is greatly reduced, and the economic effect is very significant. 7. Titanium in the papermaking and textile industries has special anti-corrosion properties for chlorine dioxide, chlorite, chlorite and other bleaching agents. Therefore, titanium has important applications in the bleaching equipment of the textile printing and dyeing industry and papermaking industry. For example, sub-drifters made of titanium materials work well. At the same time, there are also spinnerets used in industries such as synthetic fibers. 8. In other aspects, titanium can resist human body corrosion and is harmless to the human body. Therefore, it can be widely used in the medical and pharmaceutical industries. Titanium has good suction performance and is also widely used in electronic vacuum technology and high vacuum technology.
