There are several methods of hardening special steel, each with its own advantages and applications. 1. Quenching: This is a common method used to harden steel. It involves heating the steel to a critical temperature and then rapidly cooling it by immersing it in a quenching medium such as oil, water, or air. This rapid cooling causes the formation of a martensitic structure, which is harder and more brittle than the original steel. 2. Tempering: After quenching, the steel is often tempered to reduce brittleness and improve toughness. Tempering involves reheating the hardened steel to a specific temperature and holding it at that temperature for a predetermined amount of time. This process helps to reduce internal stresses and improve the overall mechanical properties of the steel. 3. Case hardening: This method is used to increase the hardness of the outer layer of steel while maintaining a tough and ductile core. Case hardening involves introducing carbon or nitrogen into the surface of the steel through processes like carburizing or nitriding. This creates a hard surface layer while maintaining the desired properties in the core. 4. Induction hardening: This technique is commonly used for specific areas of a component that require localized hardening. It involves using an electromagnetic field to heat only a specific region of the steel, followed by rapid quenching. Induction hardening provides precise control over the hardened area while maintaining the desired properties in the rest of the component. 5. Cryogenic treatment: This method involves subjecting the hardened steel to extremely low temperatures, often below -150°C (-238°F). This process helps to further refine the microstructure of the steel, improving its hardness, wear resistance, and dimensional stability. 6. Flame hardening: This method involves heating the surface of the steel using a high-temperature flame and then quenching it. Flame hardening is commonly used for large components or areas that require localized hardening. It is important to choose the appropriate method based on the specific requirements of the steel and the intended application. The selection of the method depends on factors such as the desired hardness, toughness, wear resistance, and dimensional stability of the steel.
