Abstract
SummaryIn laboratory researches and food packing tests, it has been shown that cold rolled steel strip, plated with a thickness of about 0·002 mil (0·05 μ) of chromium and coated with lacquer is a satisfactory material for cans. It is highly resistant to corrosion, especially to sulphur staining, and the lacquer coating remains firmly adherent. In food packing tests with it, the chromium content of the foodstuffs was no greater than it was with tinplate. The chromium plating line is similar in layout to an electrolytic tinning line, but insoluble electrodes are used and the electrolyte contains chromic and sulphuric acids. For high-speed operation with several plating tanks, special screening of part of the cathode is used to obtain a better lustre.
