Thermal fatigue occurs when a material is subjected to repeated heating and cooling cycles, leading to the formation of cracks and eventual failure of the material. Special steel is specifically designed to withstand extreme temperature changes. It has a high melting point and excellent thermal conductivity, which allows it to efficiently dissipate heat and minimize thermal stress. Additionally, the steel is often alloyed with elements such as chromium, nickel, and molybdenum, which enhance its resistance to thermal fatigue. The alloying elements in special steel form a protective layer that acts as a barrier against oxidation and corrosion. This protective layer prevents the formation of cracks and improves the steel's ability to withstand thermal cycling. Furthermore, the alloying elements improve the steel's structural integrity by promoting the formation of fine and evenly dispersed microstructures. This enhances the steel's toughness and resistance to cracking. Moreover, special steel undergoes various heat treatment processes to further enhance its resistance to thermal fatigue. These processes involve controlled heating and cooling cycles, which refine the microstructure of the steel and make it more resistant to deformation and cracking. The heat treatment also helps in relieving any residual stresses that may have been induced during the manufacturing process. In summary, special steel resists thermal fatigue through its unique composition, alloying elements, and heat treatment processes. Its high melting point, excellent thermal conductivity, and protective layer against oxidation and corrosion make it highly resistant to thermal cycling. The refined microstructure and relieved residual stresses further enhance its ability to withstand repeated heating and cooling cycles without failure.
