Härdning

Härdning är en värmebehandlingsprocess som huvudsakligen används för stål för att öka hårdhet, hållfasthet och slitstyrka. Metallen värms upp över sin kritiska temperatur (vanligtvis 750–900 °C beroende på kolhalten) tills strukturen blir austenit. Därefter kyls den snabbt (släcks) i vatten, olja, polymerlösning eller luft.

Snabb kylning omvandlar austenit till martensit, som är mycket hård men spröd. Härdning följs vanligtvis av anlöpning.

Ugnstyper som används:

  • Elektrisk muffelugn
  • Kammarugn
  • Induktionsugn
  • Saltbadugn

Tillämpningar:

Skärverktyg, formar, kugghjul, axlar, lager
