Annealing Envelopes

Annealing envelopes

  • Annealing envelopes useful up to Tmax 1200 °C
  • For hardening small parts
  • Airtight lock by means of folds of a fold lock or suitable tools
  • 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

Annealing Bags

Annealing bags

  • Annealing bag suitable for powder nitriding, boriding and high speed steel hardening up to approx. 1050 °C - 1150 °C for cold work purposes
  • Made of stainless steel heat treating foil for single use
  • For hardening of blocks, stamps, cutting plates, etc.
  • Rapid heating binds the oxygen in the annealing bag so that high-alloy and medium-alloy steel grades can be hardened
  • Rapid quenching in air, oil or water, ensuring high dimensional accuracy
  • Workpieces are placed as tightly as possible into the annealing bag
  • Airtight lock by means of folds of a fold lock or suitable tools
