heat treatment: induction hardening

Induction hardening

With induction hardening, the edge of a workpiece is heated quickly and then quenched by the plant (hardened). Long cylindrical components can be hardened inductively using our medium-frequency hardening system (hardening length of up to 5,000 mm).

Advantages of this heat treatment

  • High surface hardness, tough core
  • Improves resistance to wear and tear
  • Partial hardening
  • High reproducibility


  • Tempered steels
  • Tool steels
  • Stainless steels
  • Casting materials

Available plant sizes

Plant HF, length 800 mm, diameter 100 mm
Plant MF, length 5000 mm, diameter 400 mm
