Which materials are typically used in the construction of pressure vessels?

The choice that lists steel, stainless steel, and other alloys accurately reflects the materials commonly used in the construction of pressure vessels. These materials are favored due to their high strength, durability, and resistance to deformation under high pressure.

Steel is particularly prevalent because it offers excellent tensile strength and can withstand significant internal pressures, making it suitable for a wide variety of applications, including oil and gas, chemical processing, and power generation. Stainless steel is employed for its corrosion-resistant properties, which extend the life of pressure vessels, especially in environments where the vessel may be exposed to corrosive substances. The use of various other alloys allows for customization of material properties to meet specific operational requirements and challenges such as temperature fluctuations and chemical exposure.

Materials like plastic, rubber, and wood are not suitable for pressure vessel construction since they generally lack the necessary strength and stability to handle the extreme pressures involved. Similarly, while aluminum and fiberglass might serve other structural roles, they do not offer the same level of safety and performance as steel-based materials for high-pressure scenarios. Bronze, copper, and lead, although used in some specialized applications, do not provide the required mechanical strength or impact resistance for the majority of pressure vessel applications.
