Heat Treatment

Soft Annealing / Solution Annealing

Solution annealing should take place at temperatures of between 1,100 and 1,160°C (2,012 and 2,120°F).

Fast air cooling can also be carried out at thicknesses of less than approx. 1.5 mm (0.059 in). In the process, the cooling must take place within 2 minutes between 1,000 and 600°C (1,832 and 1,112°F).
