UNI X10CrNi18-8 Heat Treatments

  • Heat treated at 250-425°C; Duration: 30 min to 4h; Air cooling; The optimum heat treatment conditions may be very different. The spring manufacturer shall choose those conditions answering the purpose; The heat treatment data refer to compression springs, torsion and tension (springs without initial tension); The lower temperature is recommended for extension springs with prestress.
  • Heated: 250-425°C (30 min. to 4 h), air cooling.
