Ricottura dolce

La ricottura dolce viene utilizzata principalmente per acciai ad alto contenuto di carbonio per ridurre la durezza e migliorare la lavorabilità. L’acciaio viene riscaldato leggermente sopra la temperatura critica inferiore e raffreddato lentamente.

Questo processo produce una struttura sferoidizzata.

Intervallo di temperatura:

  • 650–750°C

Tipi di forno utilizzati:

  • Forno a camera
  • Forno a campana
  • Forno ad atmosfera controllata

Applicazioni:

Acciai per utensili prima della lavorazione meccanica
