Flame hardening vs induction hardening

WebJun 3, 2024 · Induction hardening has several benefits over other hardening methods. It is easier to control b ecause it is an electrical process rather than a combustion process. Another benefit is that it begins heating the surface of the material, rather than the core. This makes induction hardening an excellent option for case hardening.
