ÖNORM EN 10271

1.1 This European Standard specifies requirernents for continuously electrolytic zinc-nicke1 coated cold rolled flat products of low carbon steels suitable for cold forming according to table 1 and table 2 in rolled widths 2 600 mrn and thicknesses from 0,35 mm up to and including 3 mrn, 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-nicke1 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-nicke1 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 zincnicke1 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 lOl47), - electrolytically zinc coated cold rolled flat products (see - continuously hot-dip aluminium-silicon (AS) coated steel strip and sheet (see EN 10154). - continuously organic coated steel flat p (...abbreviated)
