One industrial client initially selected carburizing for their new clutch springs after hearing about its benefits. Duk da haka, the process resulted in dimensional distortion that required expensive straightening operations. After switching to induction hardening, they achieved similar hardness with zero distortion and reduced energy consumption. This shift improved productivity while enhancing spring performance.
What Materials Respond Best to Surface Hardening?
