Distensione (Ricottura di distensione)

La distensione elimina le tensioni residue indotte da saldatura, lavorazioni meccaniche o deformazione a freddo senza modificare significativamente le proprietà meccaniche.

Il metallo viene riscaldato a una temperatura più bassa (450–650°C) e raffreddato lentamente.

Tipi di forno utilizzati:

  • Forno elettrico
  • Forno a gas
  • Forno a carica (batch)

Applicazioni:

Strutture saldate, basamenti di macchine, recipienti in pressione
