Tracking the magnetism of charging racks

Charging racks for the gas carburizing process are subject to incipient magnetism after a certain period of use.

In the as-delivered condition, the alloy 1.4855 (or 1.4849) is completely non-magnetic. The aim of the investigations was to determine the cause of the magnetism in order to be able to derive containment actions. By means of spectral analysis, metallography and scanning electron microscopy, we were able to get to the bottom of the cause. If you have similar problems with your charging racks, please contact us.
