UNI X5CrNiN19-9 Heat Treatments

Heat treated at 350-400°C; Duration: 30 min to 1h; 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).
Hot working (air cooling): 1150-850°C; +AT - Solution annealing (air or water cooling): 1000-1100°C.

Hot formed conditions:
1U - Hot formed, not heat treated, not descaled.
1C - Hot formed, heat treated, not descaled.
1E - Hot formed, heat treated, mechanically descaled.
1D - Hot formed, heat treated, pickled, coated (optional).
1X - Hot formed, heat treated, rough machined.
1G - Hot formed, heat treated, descaled, rough machined or shaved in the case of rod.
Cold processed conditions:
2H - Finishes 1E, 1D or 1X, cold processed, coated (optional).
2D - Finish 2H, heat treated, pickled and skin- passed (optional), coated (optional).
2B - Finishes 1E, 1D or 1X, cold processed, mechanically smoothed.
2G - Finishes 2H, 2D or 2B, centreless ground, mechanically smoothed (optional).
P - Finishes 2H, 2D, 2B or 2G, specular polishing.
