Heat Treatment
Heat treatment use electromagnetic induction to rapidly and precisely heat conductive materials, enabling localized, efficient, and repeatable surface hardening, annealing, and tempering
- Annealing: Heating a metal to a specific temperature and cooling it slowly (often in a furnace) to soften it, improve ductility, and relieve internal stresses.
- Normalizing: Similar to annealing but involves air-cooling to create a more uniform and refined grain structure, making the metal tougher.
- Hardening: Heating the metal and then Quenching it rapidly in water, oil, or brine to increase its hardness and strength.
- Tempering: Following hardening, the metal is reheated to a lower temperature to reduce the brittleness caused by quenching while maintaining most of the hardness.
- Case Hardening: A process like Carburizing that adds carbon or nitrogen to the surface layer of a part, creating a hard, wear-resistant exterior while keeping a tough, ductile core.
