What material is commonly used in the construction of boiler tubes for high-pressure applications?

Carbon steel is commonly used in the construction of boiler tubes for high-pressure applications due to its excellent mechanical properties, cost-effectiveness, and ability to withstand high temperatures and pressures. Carbon steel can be alloyed with other elements to enhance its properties, making it suitable for various boiler configurations and environments. It also exhibits good fatigue resistance and tensile strength, which are critical for the safety and efficiency of high-pressure boilers.

In high-pressure applications, the material must be able to endure the conditions without deforming or failing. Carbon steel meets these demands, especially when properly treated and maintained within its designed temperature and pressure specifications. Its widespread use in the industry is complemented by the availability and lower cost compared to alternatives like stainless steel or aluminum, which may not provide the same durability or performance in high-stress situations.
