In marine environments, special steel, also known as stainless steel, exhibits exceptional performance in terms of resisting corrosion. This is mainly attributed to the high levels of chromium and nickel present in its alloy composition. The chromium content creates a protective oxide layer on the steel's surface, commonly referred to as the passive layer. Acting as a shield, this layer prevents direct contact between the steel and corrosive elements found in marine environments, such as saltwater. Furthermore, the presence of nickel enhances the corrosion resistance of special steel. Nickel not only improves the stability of the passive layer but also increases its ability to self-repair if it becomes damaged. This property makes special steel highly reliable and long-lasting, especially in marine environments where the steel is exposed to saltwater, high humidity, and fluctuating temperatures that can accelerate corrosion processes. Moreover, special steel offers excellent resistance to two common types of corrosion encountered in marine environments: pitting corrosion and crevice corrosion. Pitting corrosion occurs when localized areas of the steel's surface are attacked, resulting in small pits or holes. Crevice corrosion, on the other hand, takes place in confined spaces such as gaps or joints, where stagnant water or debris can accumulate and expedite corrosion. By effectively resisting these types of corrosion, special steel ensures its durability and integrity in marine applications. Overall, the high chromium and nickel content of special steel contribute to its outstanding corrosion resistance in marine environments. Its ability to form a protective passive layer, resist pitting and crevice corrosion, and self-repair makes it the preferred choice for various marine applications, including shipbuilding, offshore structures, and seawater desalination plants.

The unique composition and manufacturing process of special steel result in enhanced heat resistance, making it an ideal material for applications exposed to extreme heat conditions. Special steel is designed to have a high melting point, which means it can endure higher temperatures compared to standard steel. This is achieved by incorporating alloying elements such as chromium, nickel, molybdenum, or vanadium, which improve the steel's ability to withstand heat. These elements form stable oxide layers on the surface of the steel, acting as a barrier against oxidation and preventing the steel from losing strength or becoming brittle when exposed to high temperatures. Furthermore, special steel is often treated with heat-resistant coatings or undergoes specialized heat treatment processes to enhance its heat resistance even further. These treatments can include quenching and tempering, annealing, or precipitation hardening, depending on the specific requirements of the product. These processes alter the steel's microstructure, improving its resistance to thermal fatigue, creep, and thermal shock. The heat resistance provided by special steel allows for the creation of products that can operate in demanding environments such as aerospace, automotive, power generation, and industrial applications. For instance, in the aerospace industry, special steel is used to manufacture components like turbine blades that are exposed to extremely high temperatures in jet engines.
