Case hardening is an important part of heat treating and is particularly useful for the manufacture of machine parts, carbon steel forgings, and carbon steel pinions.
In many metallurgical applications, strength is of minor importance and wear resistance is the primary consideration. In other applications where wear resistance is still the prime consideration, a high level of strength and considerable toughness are also required. Achieving these conditions requires specialized techniques that create a relatively thin, hardened surface layer on the steel. This surface layer is called the “case,” and the process that creates it is known as “case hardening.” This self-guided digital course uses detailed visuals, narrated animations, and interactive quizzes to present the key case hardening processes including:
- Carburizing, carbonitriding, and nitriding
- Quenching of case hardened parts
- Induction hardening
- Various furnace types used in commercial heat treating processes
