ALUMINISED AND STAINLESS STEEL DISCOLOURATION
This report presents two investigations measuring discolouration on the steels used for making quartz cassettes, aluminised steel and stainless steel. It shows results of furnace tests on stainless steel samples and also includes supporting material from a previous investigation into aluminium clad steel.
In this trial, twelve samples of stainless steel were placed in an electric thermostatically controlled kiln and allowed to soak for 30 minutes at temperatures ranging from 150°C to 600°C.
The results are shown and discussed as part of this paper.
