Abstract

1.1 This European Standard specifies requirements for continuously electrolytic zinc-nickel coated cold rolled flat products of low carbon steels suitable for cold forming according to table 1 and table 2 in rolled widths >= 600 mm and thicknesses from 0,35 mm up to and including 3 mm, delivered as strip (in coil form), sheet, slit strip or cut lengths obtained from slit strip or sheet. The coating is composed of Zn with a Ni-content of 10,5 % to 13 %. 1.2 This European Standard may also be applied to the coating requirements of continuously electrolytic zinc-nickel coated cold rolled flat products of a) steels according to EN 10139 (cold rolled strip in rolled widths < 600 mm), b) other types of low carbon steel for cold forming, c) steels normally characterized by minimum yield strength values in addition to formability parameters, e. g. - steels with high yield strength and improved formability according to EN 10268 or other microalloyed steels, - rephosphorized steels and bake-hardening steels, - general purpose structural steels. 1.3 By special agreement at the time of ordering this European Standard may be applied to the coating requirements of continuously electrolytic zinc-nickel coated hot-rolled steel flat products (e.g. according to EN 10025, EN 10111, EN 10149-1 to EN 10149-3 etc.). 1.4 The coating masses, surface qualities and surface finishes are given in 5.9, 5.11 and table 3. As the mass of the zinc-nickel coating applied is relatively small, the material is not intended to withstand outside exposure without further chemical treatment and painting. 1.5 This European Standard is not applicable to - hot-dip zinc coated steel strip and sheet (see EN 10142 and EN 10147), - electrolytically zinc coated cold rolled flat products (see EN 10152), - continuously hot-dip aluminium-silicon (AS) coated steel strip and sheet (see EN 10154). - continuously organic coated steel flat products (see EN 10169), - continuously hot-dip zinc-aluminium (ZA) coated steel strip and sheet (see EN 10214), - continuously hot-dip aluminium-zinc (AZ) coated steel strip and sheet (see EN 10215).
