When selecting between carburizing and induction hardening, several points need to be considered including material, load conditions and cost.
- Carburizing is applied to low carbon alloy steel, offering deeper case depth and superior resistance to heavy loads and contact fatigue, though it requires longer processing time and brings higher cost.
- Induction hardening produces a relatively shallow hardened layer with higher efficiency and lower cost. It works well for components under moderate wear load without severe impact.
