SIST EN 2280:2018

Overview

EN 2280:2018 is a CEN/Aerospace series material standard that defines requirements for steel FE‑PM37 in sheet form for aerospace applications. The standard addresses high‑strength steel sheets with tensile strength Rm in the 900–1 100 MPa range and thickness a ≤ 6 mm. EN 2280:2018 is intended to ensure consistent material chemistry, processing, heat treatment and testing so that manufacturers and purchasers can specify steels suitable for aviation and aerospace components.

Key Topics

• Material designation: Steel FE‑PM37 (a defined aerospace series material).
• Mechanical range: Specified tensile strength Rm = 900–1 100 MPa (as given in the document title).
• Thickness/form: Sheet products with maximum nominal thickness ≤ 6 mm.
• Chemical composition: Specified element ranges are given in the standard. Representative bounds in the document include:
  • C: min 0.08% - max 0.13%
  • Si: max 0.35%
  • Mn: max 0.90%
  • Cr: ~11.0–12.5%
  • Mo, Ni, V and N are also specified with minimum/maximum limits in the table of requirements.
• Production method: Specified as air melted.
• Delivery conditions and heat treatment: The standard includes delivery conditions such as softened and hardened & tempered; a reference heat treatment is provided (e.g. austenitizing and tempering regimes are indicated in the document).
• Testing and inspection: EN 2280 references mandatory testing, marking and dimensional inspection requirements; optional and mandatory tests are defined in the requirements table. Product qualification programmes are to be agreed between manufacturer and purchaser.

Applications

EN 2280:2018 is targeted at the aerospace and defence industries where predictable high strength and controlled metallurgical quality are essential. Typical applications and benefits include:

• Use in aircraft structural parts and assemblies where high tensile strength and controlled toughness are required.
• Reliable procurement specification for manufacturers and purchasers, reducing ambiguity in material acceptance.
• Clear guidance on composition, production route and heat treatment to support consistent mechanical properties and performance in service.

Related Standards

EN 2280 references and is organized in accordance with other Aerospace series standards. Relevant linked standards in the document include:

• EN 4258 - General organization of aerospace metallic material standards.
• EN 4500-005 - Rules for drafting and presentation of metallic material standards (specific rules for steels).
• EN 4700-001 - Technical specification for steel wrought products (plate, sheet and strip).

For procurement or engineering use, refer to EN 2280:2018 together with these referenced standards to ensure full compliance with testing, heat treatment and documentation requirements. Where not explicitly covered, product qualification and special inspection criteria should be agreed between purchaser and supplier.
