The materials used in the construction of liquid oxygen tanks typically need to have excellent low-temperature resistance and corrosion resistance. Common materials for making liquid oxygen tanks include:
Stainless Steel: A commonly used material for making liquid oxygen tanks, stainless steel boasts excellent corrosion resistance and mechanical strength. Common stainless steel grades include 304 and 316.
Aluminum Alloy: Aluminum alloys are also commonly used in the manufacturing of liquid oxygen tanks, offering low density and excellent corrosion resistance. Common aluminum alloy materials include 5083 and 6061 aluminum alloys.
Fiberglass Reinforced Plastic (FRP): FRP is a composite material made up of glass fibers and resin. It boasts excellent corrosion resistance and mechanical strength, making it suitable for liquid oxygen storage tanks in some special environments.
碳钢（Carbon Steel）：碳钢是一种常见的储罐制作材料，具有较高的强度和耐腐蚀性。然而，碳钢在液氧环境下容易发生氧化反应，因此需要采取防腐措施。
It's important to note that the choice of materials for liquid oxygen storage tanks should be determined based on specific application requirements, working conditions, and safety standards. When selecting materials, consider the properties of liquid oxygen and the design requirements of the tank to ensure safety and reliability. Additionally, manufacturers and suppliers often provide material selection advice and technical support.

Liquid oxygen storage tanks may deform during use. The following are common deformation defects found in liquid oxygen storage tanks:
Elastic Deformation: Liquid oxygen tanks may undergo elastic deformation when subjected to external pressure or temperature changes. This deformation is typically reversible, meaning the tank will return to its original shape once the external pressure is removed or the temperature returns to normal.
Plastic Deformation: When a liquid oxygen tank is subjected to significant external force or pressure, it may experience plastic deformation. This deformation is irreversible, and the tank cannot return to its original shape. Plastic deformation can cause changes in the tank's shape, such as dents or warping.
Hot Deformation: Liquid oxygen storage tanks may experience hot deformation when subjected to high temperatures or temperature changes. Hot deformation can cause the tank to change shape, expand, or contract.
Cold Deformation: Liquid oxygen tanks may experience cold deformation when subjected to low temperatures or temperature changes. Cold deformation can cause the tank to change shape, contract, or crack.
These deformation defects may affect the structural integrity and safety of liquid oxygen storage tanks. Therefore, it is important to regularly inspect and assess the deformation of liquid oxygen storage tanks to ensure their normal operation and safe use. If deformation defects are found in the tanks, prompt repair or replacement measures should be taken to avoid further damage and safety risks.

The use of liquid oxygen storage tanks requires special attention to the following safety matters:
Training: Personnel handling liquid oxygen tanks must undergo training to understand the properties of liquid oxygen, safety operating procedures, and emergency response measures. Only trained personnel are authorized to operate liquid oxygen tanks.
Safety Operating Procedures: Establish and adhere to the safety operating procedures for liquid oxygen storage tanks, including proper operational procedures, protective measures, and emergency response plans. Ensure that operators follow the procedures to minimize accident risks.
Protection Measures: When using liquid oxygen tanks, necessary protective measures must be taken, such as wearing protective gloves and suits. Avoid direct contact with liquid oxygen to prevent frostbite.
Leak Control: Regularly inspect the liquid oxygen storage tank for leaks and equip with leak detectors and alarm systems. In case of a leak, immediate measures should be taken to control the leak and conduct repairs.
Fire Prevention Measures: Liquid oxygen contains a high oxygen concentration, making it prone to fire. To prevent and contain fires, fire barriers and fire-retardant coatings should be installed around liquid oxygen storage tanks.
Static protection: Electrostatic buildup in liquid oxygen tanks may cause sparks, increasing the risk of fire. Measures such as using static-conductive materials and anti-static equipment are taken to reduce the accumulation and release of static electricity.
Ventilation Requirements: Ensure adequate ventilation within the enclosed space of the liquid oxygen storage tank to expel vapors produced by the evaporation of liquid oxygen.
