Overview

EN 4466:2007 is a European standard developed by CEN for the aerospace sector. It specifies the requirements for steel FE-PM1506 (X5CrNiMoAl13-8-2), a high-strength, corrosion-resistant stainless steel, particularly when produced as forgings with a maximum diameter or thickness (a or D) of 150 mm and a minimum tensile strength (Rm) of 1,400 MPa. The material must be vacuum induction melted and consumable electrode remelted, followed by solution treatment and precipitation hardening to ensure the required mechanical properties and reliability for critical aerospace components.

This standard is vital for organizations that manufacture or source steel forgings used in aircraft and aerospace applications, ensuring consistency, safety, and quality across the supply chain.

Key Topics

• Material Designation and Composition
  • Steel type FE-PM1506, also known as X5CrNiMoAl13-8-2, is characterized by its specific alloy composition, combining chromium, nickel, molybdenum, and aluminum for enhanced mechanical properties.
• Production Process
  • The steel must be produced through vacuum induction melting and consumable electrode remelting, processes that guarantee high purity and controlled microstructure.
• Heat Treatment
  • The forgings must undergo both solution treatment and precipitation hardening to achieve optimal strength and performance characteristics.
• Dimensional Requirements
  • Applicable to forged parts where either the thickness or diameter does not exceed 150 mm, ensuring the material’s mechanical consistency within this range.
• Mechanical Properties
  • Forgings must demonstrate a minimum tensile strength (Rm) of 1,400 MPa, making them suitable for demanding aerospace environments.
• Testing and Inspection
  • Reference is made to EN 2157-3 for technical specifications and testing requirements, as well as additional standards for defect detection and quality assurance.

Applications

EN 4466:2007 plays a crucial role in the aerospace industry, where components must meet strict performance and safety standards. Typical applications include:

• Aerospace Forgings: Used extensively in high-stress areas such as landing gear, engine mounts, structural supports, and fasteners where both strength and corrosion resistance are critical.
• High-Strength Components: Suitable for manufacturing parts that are subjected to extreme loads, fatigue, and varying environmental conditions due to the material’s high tensile strength and excellent durability.
• Critical Flight Parts: The combination of advanced melting techniques and stringent heat treatment protocols ensures these forgings meet the reliability needs for aircraft and space vehicles.

Compliance with EN 4466:2007 provides manufacturers, suppliers, and aerospace operators with confidence in the consistency and safety of their forged steel components, reducing variability and supporting regulatory approval and airworthiness certification.

Related Standards

EN 4466:2007 references and interrelates with several other important European standards. Key related standards include:

• EN 2157-3: Technical specification for aerospace steel forgings, covering production and inspection protocols.
• EN 2857-2: Specifies requirements for magnetic particle inspection in aerospace, a key process for detecting surface and near-surface discontinuities in steel forgings.
• EN 4258: Describes the general organization and links between types of EN standards for metallic materials in aerospace applications.
• EN 4347: Sets requirements for softened forging stocks of steel FE-PM1506, supporting the upstream supply and traceability of the material.
• EN 4500-5: Contains rules for drafting and presenting material standards in aerospace, with specific guidance for steels.

These standards work in conjunction to ensure quality control, traceability, and compliance in the aerospace manufacturing process, supporting the objectives of EN 4466:2007 and strengthening the overall aerospace supply chain.
