• Nitriding or carburizing atmospheres
• 1562–1742°F (850–950°C) maximum

HEAT TREATMENT

1. Annealing: This process involves heating the material to a specific temperature and holding it there for a period of time to soften the metal. Annealing can help reduce stress, improve ductility, and make the material easier to work with.

2. Quenching: This process involves quickly cooling the material after it has been heated. Quenching can be used to harden the metal and improve its strength, but it can also make the material more brittle if not done properly.

3. Tempering: This process involves heating the metal to a specific temperature and then allowing it to cool slowly. Tempering can help improve the toughness and ductility of the material, making it less likely to crack or fail under stress.

4. Stress Relieving: This process involves heating the material to a specific temperature and maintaining it there for a period of time to relieve any residual stress that may be present. Stress relieving can help improve the overall durability and lifespan of the material.

5. Normalizing: This process involves heating the material to a specific temperature and then allowing it to cool in air. Normalizing can help improve the overall consistency of the material and reduce any internal stress that may be present.
