Q: How does special steel resist oxidation at high temperatures?: Due to the presence of specific alloying elements and a carefully controlled manufacturing process, special steel is able to resist oxidation at high temperatures. When exposed to oxygen in the air, alloying elements like chromium, nickel, and aluminum form a protective oxide layer on the steel's surface. This layer acts as a barrier, preventing further oxidation. Of these alloying elements, chromium is particularly effective in forming a stable and dense chromium oxide layer. This layer serves as a self-healing mechanism, meaning that if it becomes damaged or scratched, it will quickly regenerate and continue to protect the steel from oxidation. The manufacturing process of special steel involves precise control of composition and heat treatment. This ensures that the steel has a fine and uniform microstructure, minimizing the presence of impurities or defects that could speed up oxidation. Moreover, the steel often undergoes various heat treatments, such as annealing or quenching, which further enhance its resistance to oxidation.
