ABSTRACT:
Tin-free steel having a first layer of metallic chromium on a steel base and a second layer of hydrated chromium oxide on the first layer, in which the atomic ratio of sulfur and the atomic ratio of fluorine to the sum of chromium, oxygen, sulfur and fluorine in the second layer are respectively not greater than 2.5 atomic percent and not greater than 10 atomic percent. This tin-free steel can be used for a nylon-adhered can body to be subjected to a hot-packing or retort treatment, since it has excellent lacquer adhesion after aging in hot water and under retort conditions.
