Abstract
A process for improving the rust and corrosion resistance of thinly coated tinplate is disclosed, wherein a steel sheet coated with 0.02-0.2 g/m.sup.2 of nickel prior to annealing is coated with 0.05-1.5 g/m.sup.2 of tin, subsequently being trated with 0.3-10 C/dm.sup.2 of chromate and then subjected to a treatment of melting tin (reflow). A layer of alloy thus formed is highly rust resistant and structurally different from any of those formed on thinly coated tinplate according to the prior art, so that highly rust resistant tinplate sheets for use in the manufacture of welded cans can be obtained.
