Overview
EN 10268:2006+A1:2013 is a CEN European Standard that specifies technical delivery conditions for cold‑rolled, uncoated steel flat products with high yield strength intended for cold forming. It covers products with a thickness of ≤ 3 mm, delivered as sheet, wide strip, slit wide strip, narrow strip or cut lengths. The standard defines chemical composition, mechanical properties, delivery conditions, testing, marking and packing for a range of high‑strength cold‑rolled grades (e.g., HC180Y, HC220B, HC260LA, HC300I, HC500LA).
Key topics and requirements
- Scope & product forms: Cold rolled uncoated flat products for cold forming - sheets, coils, strips and cut lengths (thickness ≤ 3 mm).
- Chemical composition: Mandatory ladle analysis limits are given per grade (C, Si, Mn, P, S, Al, Ti, Nb and other microalloying elements). Grades include bake‑hardening (B), interstitial‑free (Y), isotropic (I) and low‑alloy/micro‑alloyed (LA) designations.
- Mechanical properties: Transverse test requirements are specified (0.2% proof strength Rp0.2, tensile strength Rm, elongation A80, plastic strain ratio r and strain‑hardening exponent n). Bake‑hardening (BH2) minimum increases are defined for B grades.
- Delivery condition: Products are supplied skin‑passed and typically oiled (neutral non‑drying oil protecting for up to three months unless otherwise agreed).
- Surface and formability: Surface quality and finish symbols (A, B, finish codes) are included. Suitability for surface coating and weldability requirements are addressed.
- Testing & inspection: Sampling, number of tests, inspection units, test methods and inspection documents follow the normative references (e.g., tensile and sampling standards).
- Designation and marking: Clear designation rules (example: Sheet EN 10268‑HC260LA‑A‑m) and marking/packing requirements are provided.
- Tolerances & disputes: Dimensional tolerances, shape tolerances and dispute resolution procedures are referenced.
Practical applications
- Automotive body panels, deep‑drawn components and structural parts requiring high yield strength and controlled formability.
- Manufacturers producing cold‑formed components where consistent mechanical properties, bake‑hardening behavior or high formability are critical.
- Supply chain roles: steel producers, coil/strip converters, OEM purchasing, quality/QA engineers and testing laboratories rely on EN 10268 for specification and acceptance criteria.
Who should use this standard
- Steel mills and cold‑rolling mills specifying or producing high‑strength cold‑rolled sheet/strip.
- Component manufacturers and stampers specifying material for cold forming, deep drawing or dent‑resistant panels.
- Engineers, procurement and QA teams drafting purchase orders, inspection plans and conformity documentation.

3.3 high strength interstitial free steels (Y) steels whose composition is controlled to achieve improved plastic strain ratio r and strain hardening exponent n values Note 1 to entry: These steels have both a high mechanical strength and an excellent suitability for cold forming due to their solid solution hardening and interstitial free microstructure. They are used for complex components involving deep drawing processes. 3.4 isotropic steels (I) steels with limited plastic strain ratio r value Note 1 to entry: These steels have excellent stretch formability due to their isotropic behaviour. They are used in the automotive industry for bonnets and doors." 4 Designatio
