Heat treatment

6.3.1 Annealing of wires

Spring hard chrome nickel stainless steel wires (e. g. remanium
temperature of approx. 1100 °C / 2012 °F (heat color bright red).
Soft annealed CoCr wires cannot be tempered (hardened)!
C omplex bending operations (especially around tight radii with thick wires, e. g. outer wires
of face bows) should not be done without previous local annealing of the bending area.
Soft annealing is also recommended for removing the elasticity from a wire over a certain length,
e. g. with a passive lingual or palatal bow. Refer to 6.3.4 for the subsequent procedure.

6.3.2 Tempering wires

Cobalt based alloys, e. g. remaloy
the wire elements depends on the time and the temperature. Heat the wire element only briefly
using the hand electrodes (heat color: dark brown) at a temperature of approx. 470 °C / 878 °F.
In view of the different wire dimensions, it is recommended to determine the optimum hardening
conditions experimentally beforehand. Refer to 6.3.4 for the subsequent procedure.
