Abstract

El acero al carbono regular puede producirse esencialmente igual al acero galvanizado en resistencia a la corrosión, después de pintarse con una pintura flexible moderna del tipo preferido para un revestimiento en la industria de aparatos, tratando primero la superficie de acero para depositar una cantidad pequeña de níquel sobre la superficie y luego secando en su sitio un revestimiento de una composición que contiene cromo hexalente y de preferencia también como trivalente, sílice y iones de fosfato.Regular carbon steel can be produced essentially the same as galvanized steel in corrosion resistance, after painting with a modern flexible paint of the preferred type for a coating in the appliance industry, first treating the steel surface to deposit a small amount of nickel on the surface and then drying in place a coating of a composition containing hexalent chromium and preferably also as trivalent, silica and phosphate ions.
