Overview

EN 2366:2019 is a CEN standard that specifies the dimensions and tolerances for cold‑rolled sheets and strips made from heat‑resisting alloys used in aerospace construction. The standard covers products with thickness a ≤ 3 mm and complements material requirements referenced in the relevant material standards. Sheets and strips supplied to EN 2366:2019 shall also conform with the requirements of EN 4700.

Key Topics

• Preferred thicknesses: the standard lists preferred thicknesses from 0.3 mm up to 3.0 mm (e.g. 0.3, 0.4, 0.5, …, 3.0). Mass per square metre values are given, calculated on the basis of an average density of 8.1 g/cm³.
• Dimensional tolerances: tabulated tolerances for thickness, width and length are provided. Tolerances vary by thickness range and by width/length bands to ensure consistent manufacturability and interchangeability.
• Coiled strip tolerances: specific width tolerances for coiled strips are provided by thickness and width class.
• Geometrical tolerances:
  • Squareness: defined by the difference in length of diagonals |AC − BD| (table provides allowable limits by sheet size).
  • Lateral straightness: maximum admissible deviation F is 0.2% of the reference dimension (length or width).
  • Flatness: measured as the maximum distance Y between a straight reference line touching two points and the surface when the sheet/strip rests under its own mass; allowable deviations are agreed between manufacturer and purchaser and expressed as a percentage of the reference dimension X.
• Designation elements: the standard defines recommended designation components including name, material standard number, dimensions (thickness, width, length) and the dimensional standard number.

Applications

EN 2366:2019 applies to cold‑rolled, heat‑resisting alloy sheets and strips used in aerospace and defence sector structures where precise dimensions and predictable tolerances are critical for:

• Structural panels and assemblies
• High‑temperature components and shrouds
• Parts requiring close fit and interchange across suppliers

Using EN 2366:2019 supports consistent procurement, reduces rework from dimensional non‑conformity and speeds qualification of materials for aerospace manufacturing.

Related Standards

• EN 4700 (all parts) - Aerospace series: Steel and heat resisting alloy - Wrought products - Technical specification (referenced normative document).
• National implementations and language versions authorized by CEN (EN 2366:2019 exists in English, French and German).

EN 2366:2019 is intended as a practical dimensional reference for manufacturers, purchasers and engineers specifying cold‑rolled heat‑resisting alloy sheets and strips with thicknesses up to 3 mm in aerospace construction.
