Overview
EN 10271:1998 is a CEN European standard that defines the technical delivery conditions for electrolytically zinc‑nickel (Zn‑Ni) coated cold‑rolled flat steel products. It applies to low‑carbon steels suitable for cold forming and covers products delivered as coils, sheet, slit strip or cut lengths. Applicable dimensions in the scope include rolled widths ≥ 600 mm and thicknesses from 0.35 mm up to and including 3 mm. The standard specifies that the electroplated coating is composed of zinc with a nickel content of 10.5% to 13%.
Key Topics
EN 10271 focuses on the practical and quality requirements for Zn‑Ni coated steel flat products. Key technical topics typically covered include:
- Coating composition and chemistry - requirement that the electrolytic coating is Zn with Ni content in the specified range (10.5–13%).
- Product forms and dimensions - strip (coil), sheet, slit strip and cut lengths, with scope limits on width and thickness.
- Delivery conditions - definitions of supply state, surface finish and packaging suitable for transport and storage.
- Mechanical and forming suitability - ensuring the base cold‑rolled steel is appropriate for cold forming operations.
- Surface quality and appearance - acceptance criteria for coating uniformity, defects and adhesion.
- Testing and inspection - provisions for sampling, performance tests (e.g., adhesion, coating thickness), and conformity checks.
- Marking and documentation - required markings, test reports and certificates to accompany deliveries.
- Corrosion performance considerations - expectations for corrosion protection associated with Zn‑Ni coatings (standard describes testing/acceptance but does not prescribe specific service lifetimes).
(Note: specific numerical tolerances, test methods and acceptance criteria are detailed in the full standard text.)
Applications and Users
EN 10271 is relevant for organizations involved in the manufacture, specification and use of corrosion‑resistant flat steel products:
- Steel producers and platers producing electrolytically Zn‑Ni coated coils and sheets
- Automotive and transport manufacturers specifying coated steels for body panels and structural parts
- OEMs and component fabricators requiring cold‑formable, corrosion‑resistant substrates
- Procurement and quality engineers writing purchase specifications or verifying supplier conformity
- Design engineers selecting material systems for corrosion performance and forming operations
Common applications include automotive body components, stamped parts, structural assemblies and any cold‑formed components where enhanced corrosion resistance from Zn‑Ni coatings is required.
Related Standards
EN 10271 sits alongside other CEN/EN standards covering flat steel products, coatings and surface treatments. When specifying or using EN 10271 materials, consult related EN standards on cold‑rolled steel, coating test methods and corrosion testing to ensure full compliance with delivery and performance requirements.
