Hardening pockets & tins

The hardening pockets and tins are suitable for workpieces that can be packed with little air. They are made of heat-resistant steel and prevent your workpieces from scaling during the hardening process. It is suitable for both small and large workpieces. By tightly wrapping the workpiece, only a small amount of residual oxygen remains inside the hardening envelopes/hardening tins, which is completely consumed during the hardening process. The workpiece can also remain in the hardening pockets and tinss for quenching and tempering.

Practical tip
Wrap the workpiece in a layer of newspaper before hardening. This ensures that no oxygen remains inside the hardening film. Small workpieces can also be powder nitrided or boronized using the hardening pockets or tins.
