  • Rapid heating of the foil binds the oxygen in the annealing envelope preventing virtually all oxidation and decarburizing
  • Rapid quenching in air, oil or water, ensuring high dimensional accuracy
  • Workpieces are placed as tightly as possible in the annealing envelope
  • Envelopes made of ultra-thin stainless steel heat treating foil, welded on three sides, for single use
