Hardening Boxes for Models N 7 - N 161/13

Hardening boxes with lid and granulate Hardening boxes on stacker
Working with Hardening Boxes

Hardening boxes are made of heat-resistant alloy 314 (AISI)/(DIN material no. 1.4841) and also feature a lid for top charging. A ceramic fiber gasket is inserted in the circular seal profile on the upper edge of the box to seal it. To prevent oxidation during the process, neutral annealing coal is placed in the box. These bind the oxygen in the box at all temperatures. After the heat treatment, the box is removed from the oven, the lid is opened using tongs (page 22) and the workpiece removed. Our hardening boxes are also well suited for brazing. The boxes can also be used with the appropriate granulate (page 7) for carburizing (also referred to as case hardening or cementing) and for powder nitriding or powder boriding. The workpieces are placed in the box with carburizing granulate or nitriding powder or boriding powder and a suitable activator (page 7).

  • Tmax 1100 °C
  • Hardening box with lid and seal profile
  • Lid sealed with ceramic fiber, ceramic insulating materials can alternatively be used
