Titanium materials have the characteristics of high hardness, lightweight, and corrosion resistance. Due to the superior performance and characteristics of titanium materials, they are made into titanium equipment and are widely used in many fields such as industry and chemical industry.
(1) Titanium has stronger corrosion resistance than stainless steel and aluminum in many media. Moreover, titanium has a light specific gravity and high specific strength.
Titanium is easy to produce dense titanium oxide passivation film on its surface in air and oxidizing, neutral aqueous medium, which makes the electrode potential of titanium significantly positively shift and greatly improves the thermodynamic stability. The passivation coefficient is used to express the degree of improvement of the chemical stability of the metal after passivation, iron is 0.18, nickel is 0.37, molybdenum is 0.49, chromium is 0.74, aluminum is 0.82, and titanium is 2.44.
(2) Titanium does not have the low-temperature brittleness problem like ferritic steel. Titanium can be used as a low-temperature container with a temperature as low as -269 degrees, but because austenitic stainless steel, aluminum, copper, etc. can also be used as a low-temperature container, It is also cheaper than titanium, so titanium is actually rarely used in low-temperature fixed containers. In aviation and aerospace, titanium is used as a mobile cryogenic container. It is important to use titanium's high specific strength, lightweight and characteristics.
(3) Carbon steel, low alloy steel, generally stainless steel, and aluminum have poor corrosion resistance in seawater, saltwater and other chlorine-containing media. Titanium has unique and excellent corrosion resistance, and about 50% of titanium containers are used To resist the corrosion of chlorine-containing media.
(4) Since the corrosion resistance of titanium is caused by the surface oxide film, general industrial pure titanium and titanium alloys are not resistant to corrosion in strong reducing media such as high-temperature hydrochloric acid. Ti-32Mo is resistant to hydrochloric acid corrosion, but its plasticity and process properties are poor. It has not been included in the pressure processing titanium standard, nor is it included in this standard as titanium for containers.
(5) Titanium fuming nitric acid, dry chlorine, methanol, trichloroethylene, liquid dinitrogen tetroxide, molten metal salt, carbon tetrachloride and other media under certain conditions may cause combustion, explosion or stress corrosion to cause titanium container If a malignant accident occurs, titanium containers should be avoided or used with caution for these media.
(6) Titanium will burn in pure oxygen with a temperature of more than 500 degrees or in the air with a temperature of more than 1200 degrees. Therefore, the titanium container must not be exposed to open flames in contact with air and oxygen to avoid burning of the titanium container.
(7) Titanium materials and titanium containers are generally not required to assess impact toughness.
(8) Titanium has excellent corrosion resistance. More than 90% of the industrial pure titanium TA1 and TA2 are used in the civil industry to make various titanium equipment, and 3/4 of this titanium equipment are used to make titanium containers. Therefore, China's titanium container occupies a pivotal position in the titanium industry.
