The suitability of the kind of steel strip known as black plate, optionally coated with small quantities of tin or nickel for food packaging, is greatly improved by ensuring the presence of a layer of P-type semiconducting oxide on the surface thereof. The ratio of the number of Type-P charge bearing atoms (NA) of that semiconducting oxide to the numbr of Type-N charge bearing atoms (ND) is greater than 1.2. The quality of the plate is yet further improved by coating the oxide surface with a thin chromic passivation layer that also contains a P-type semiconducting oxide.
