Titanium material has strong corrosion resistance because of its strong affinity for oxygen, which can form a dense oxide film on the surface and protect titanium from medium. In most aqueous solutions, titanium can form passive oxide film on the surface. Titanium has good stability because it can generate passive oxide film in acidic, alkaline and saline solutions. It has better corrosion resistance than stainless steel and other non-ferrous metals. Due to its corrosion resistance and affinity, titanium is widely used in many industries.
(1) Chemical industry
Titanium materials have good stability in various acid, alkali and salt media.
(2) Petroleum industry
Titanium materials have very strong stability in organic compounds. Therefore, titanium is a structural material in petroleum refining and chemical industry, which can be used to make various titanium heat exchangers, titanium reactors, titanium high-pressure vessels and titanium distillation towers.
(3) Metallurgical industry
1) Titanium is an active metal with good gas absorption performance. It is a degasser in the steel making industry. Titanium can precipitate oxygen and nitrogen when the steel is cooled, making the steel tough and elastic.
2) Titanium has good corrosion resistance and stability in acidic solutions containing metal ions, so titanium electrolytic plates are widely used in the hydrometallurgical industry, such as the electrolytic production of copper, nickel, cobalt, manganese and other non-ferrous metals.
(4) Fertilizer industry
Urea is an important chemical fertilizer, which is highly corrosive under high temperature conditions. The use of titanium equipment can greatly increase the service life of the equipment and greatly reduce the maintenance time. Therefore, titanium equipment is used in urea production.
(5) Seawater desalination and shipbuilding industry
Titanium has a very good corrosion resistance to seawater, and it has special stability whether in static or high-speed seawater. Therefore, titanium is an ideal material for seawater desalination equipment. Titanium is an ideal structural material for shipbuilding industry because of its strong resistance to seawater and marine air corrosion, high strength and light weight.

(6) Electric power industry
Titanium has good stability in many corrosive hot water containing chlorides, sulfides, etc. After replacing copper nickel alloy tubes with titanium tubes, the service life can be greatly increased, the maintenance time can be reduced, and the economic effect is very significant.
(7) Medical industry
Medical titanium material It can resist the corrosion of human body and is harmless to human body. It has good biocompatibility and good comprehensive mechanical properties. Therefore, it is widely used in medical devices and pharmaceutical industries, as well as human implants.
