ABSTRACT:
The Sn based multilayer coated steel strip for container-use is improved by the provision of a novel underlying coating of ternary Fe-Ni-P alloy which, mainly because of the Ni component, ensures a uniform deposition of the Sn layer, and mainly because of the P and Fe contents ensure a satisfactory remaining amount of free Sn for improving the weldability. The steel strip has a thin Sn plated layer and a chromate coating layer on the underlying coating.
