EN 4466:2007 - Aerospace series - Steel FE-PM1506 (X5CrNiMoAl13-8-2) - Vacuum induction melted and consumable electrode remelted - Solution treated and precipitation treated - Forgings - a or D ≤ 150 mm - Rm ≥ 1 400 MPa

Overview

SIST EN 4466:2009 is a European aerospace standard developed by CEN, specifying stringent requirements for Steel FE-PM1506 (X5CrNiMoAl13-8-2). This steel grade is characterized by its vacuum induction melting and consumable electrode remelting processes, followed by solution treatment and precipitation hardening. The standard applies exclusively to forgings with a maximum diameter or cross-sectional dimension of 150 mm and guarantees a minimum tensile strength (Rm) of 1,400 MPa. It forms part of the aerospace series of metallic material standards aimed at ensuring high-performance steel components in aerospace applications.

Key Topics

  • Material Specification: Steel FE-PM1506 (X5CrNiMoAl13-8-2), known for its corrosion resistance and high strength, meets strict chemical composition limits and mechanical properties as outlined in this standard.
  • Melting and Remelting Methods: Vacuum induction melting paired with consumable electrode remelting ensures superior purity and homogeneity, optimizing mechanical performance for aerospace use.
  • Heat Treatments: The steel is solution treated (typically at ≤ 930 °C) and precipitation treated (aged at 515–535 °C for ≥ 4 hours) to achieve the required mechanical properties and microstructural stability.
  • Dimensions & Forms: Applicable for forgings up to 150 mm in diameter or section thickness, suitable for complex aerospace component geometries.
  • Mechanical Properties: Guarantees a minimum tensile strength (Rm) of 1,400 MPa, proof stress ≥ 1,300 MPa, elongation ≥ 8–9%, reduction of area ≥ 40–50%, hardness ≥ 400 HB, and adequate impact resistance.
  • Testing & Quality Control: Specifies detailed testing regimes including magnetic particle inspections, dimensional checks, grain size, and defect inspection according to related standards EN 2157-3 and EN 2857-2.
  • Documentation & Traceability: Requires precise marking and batch uniformity to ensure traceability throughout the aerospace supply chain.

Applications

SIST EN 4466:2009 steel forgings are primarily utilized in aerospace components where superior strength-to-weight ratios and corrosion resistance are critical. Typical aerospace applications include:

  • Structural aircraft components subjected to high mechanical stresses
  • Engine parts where high tensile strength and thermal stability are vital
  • Landing gear elements requiring toughness and fatigue resistance
  • Precision forgings that demand uniform metallurgical properties for safety-critical usage
  • Any aerospace system requiring certified steel forgings with guaranteed mechanical and physical properties

This standard supports aerospace manufacturers in meeting rigorous safety and performance criteria, ensuring components can withstand operational extremes encountered in flight.

Related Standards

SIST EN 4466:2009 references and aligns with a suite of related aerospace metallic material standards to form a comprehensive framework for material specification:

  • EN 4258 – General organization of aerospace metallic material standardization
  • EN 2157-3 – Technical specifications for forging stock and forgings, including pre-production and production processes
  • EN 2857-2 – Magnetic particle inspection requirements for aerospace steel forgings
  • EN 4347 – Steel FE-PM1506 in a softened state and forging stock specifications
  • EN 4500-5 – Rules for drafting and presenting aerospace steel material standards

These complementary standards ensure consistency in material quality, testing methodologies, and traceability across the aerospace industry supply chain.
