Overview
EN 10149-3:2013 (CEN) specifies the technical delivery conditions for weldable, hot‑rolled flat products made of high yield strength steels for cold forming, supplied in the normalised or normalised‑rolled condition. It supplements EN 10149-1 (general delivery conditions) and applies to plates and strip cut products with nominal thicknesses ≥ 1.5 mm and ≤ 20 mm. The standard defines grades (Table 1) and mechanical properties (Table 2) and supersedes the 1995 edition.
Key topics and requirements
- Grades and composition: Includes common grades such as S260NC, S315NC, S355NC, S420NC with ladle analysis limits for C, Mn, Si, P, S, Al and microalloying elements (Nb, V, Ti). The sum of Nb+V+Ti is limited (≤ 0.22%).
- Mechanical properties: Minimum yield strengths (ReH) of the grades (e.g., 260, 315, 355, 420 MPa) and specified tensile strength ranges and minimum elongation values are given in Table 2. Tensile test orientations depend on product width.
- Delivery condition: Products are supplied normalised or normalised‑rolled (see clause 7.2); descaled surface options follow EN 10149-1.
- Weldability and formability: Requirements and recommendations for welding, cold forming (flanging, roll forming) and suitability for flanging without cracking are addressed. Annex B provides indicative minimum inside bend radii for cold forming.
- Surface coatings: Guidance for hot‑dip zinc coating is given (EN ISO 1461 and EN ISO 14713‑2) with an option to order steels with controlled Si and P levels for improved galvanizing behaviour.
- Inspection & testing: Sampling, test‑unit definition, sample preparation (Annex A), chemical verification, tensile, bend and optional impact testing are referenced to EN 10149‑1 and the clauses of this part.
- Tolerances & dimensions: Thickness and dimensional tolerances reference EN 10029 and EN 10051 as applicable.
Applications and practical value
EN 10149-3:2013 is used to specify hot‑rolled, high‑yield steels intended for cold‑formed structural components such as:
- Automotive body and chassis parts manufactured by roll forming or flanging
- Cold‑formed sections for building envelopes and light structural members
- Galvanized steel products where coating behavior is important The standard helps purchasers, steelmakers and fabricators ensure consistent mechanical performance, weldability and formability for production and quality control.
Who should use this standard
- Steel producers and mill technical teams specifying ladle analyses and delivery condition
- Procurement/specification writers in construction and automotive industries
- Design engineers, fabricators and quality inspectors writing purchase orders or acceptance criteria
- Test laboratories performing verification to European delivery conditions
