Given the critical role that these materials play in ensuring the safe and efficient operation of power generation facilities, the requirements for special steel used in power plants are specific and stringent. Here are some of the key requirements:
1. Withstanding high temperatures: Special steel used in power plants must maintain its structural integrity even at elevated temperatures, especially in areas like the combustion chamber or steam turbines.
2. Excellent corrosion resistance: Power plants often operate in environments with high levels of moisture, chemicals, and other corrosive elements. Special steel must be able to resist corrosion to prevent degradation and premature failure.
3. High strength and toughness: Power plants generate substantial amounts of energy, so the components made of special steel must be strong and tough enough to withstand mechanical stresses and loads. This includes resistance to fatigue, creep, and stress corrosion cracking.
4. Good weldability: Welding is often necessary during the fabrication or maintenance of power plant components. Special steel should have good weldability to ensure strong and reliable joints that maintain the overall system's structural integrity.
5. Low thermal expansion: Special steel used in power plants should have low thermal expansion properties to minimize the risk of thermal stress and distortion caused by temperature variations during operation. This prevents premature failure and ensures dimensional stability.
6. Resistance to radiation: In some power plants, such as nuclear facilities, special steel may be exposed to radiation. Therefore, the steel should have good resistance to radiation damage, ensuring long-term performance and safety.
7. Compliance with industry standards: Special steel used in power plants must meet specific industry standards and codes to ensure quality, reliability, and safety. These standards may include ASTM, ASME, or ISO, among others.
Overall, the requirements for special steel used in power plants are driven by the need for high temperature resistance, corrosion resistance, strength, weldability, low thermal expansion, radiation resistance, and compliance with industry standards. Meeting these requirements ensures the integrity and longevity of power plant components, contributing to the safe and efficient generation of electricity.

1. High temperature resistance: Special steel used in power plants must be able to withstand high temperatures without losing its structural integrity. This is crucial as power plants operate at elevated temperatures, especially in areas such as the combustion chamber or steam turbines.
2. Corrosion resistance: Power plants often operate in environments with high levels of moisture, chemicals, and other corrosive elements. Special steel must possess excellent corrosion resistance to prevent degradation and premature failure caused by chemical reactions or rusting.
3. Strength and toughness: As power plants generate significant amounts of energy, the components made of special steel must exhibit high strength and toughness to withstand the mechanical stresses and loads they are subjected to. This includes resistance to fatigue, creep, and stress corrosion cracking.
4. Weldability: Power plant components often require welding during fabrication or maintenance. Special steel should have good weldability to ensure strong and reliable joints that maintain the structural integrity of the overall system.
