Overview

EN 3486:2019 is a European standard developed by CEN and ASD-STAN that specifies the technical requirements for aerospace-grade steel X3CrNiMoAl13-8-2 (1.4534). This material is solution annealed and precipitation hardened, delivering a tensile strength (Rm) between 1,400 and 1,550 MPa. The standard applies specifically to forgings with a diameter of up to 100 mm, produced for demanding aerospace applications. Known also under the ASD-STAN designation FE-PM67, this steel grade is renowned for its exceptional mechanical properties and corrosion resistance, making it ideal for high-strength aerospace components.

Key Topics

• Material Specification: Steel X3CrNiMoAl13-8-2 (1.4534), vacuum melted and consumable electrode remelted to ensure high purity and homogeneity.

• Mechanical Properties:

  • Tensile strength (Rm): 1,400 to 1,550 MPa
  • Proof stress (Rp0.2): ≥ 1,320 MPa
  • Minimum elongation: 9%
  • Reduction of area: ≥ 50% (longitudinal), ≥ 45% (longitudinal-transverse)
  • Hardness range: 43 to 47 HRC (informative)

• Heat Treatment:

  • Solution annealing at 925°C for at least 30 minutes with air cooling (AC) or oil quenching (OQ).
  • Followed by precipitation hardening at 530°C to 550°C for 4 hours with air cooling.

• Manufacturing Requirements:

  • Forgings shall comply with dimensions up to 100 mm diameter.
  • Produced according to EN 2157-3 technical specifications for forging stock and forgings.

• Testing and Quality Control:

  • Delivery conditions ensure consistency through defined heat treatments.
  • Test pieces are oriented longitudinally or longitudinal-transversely per EN 2157-3.
  • Qualification programmes agreed between manufacturer and purchaser.

• Chemical Composition (typical ranges):

  • Carbon (C): max 0.05%
  • Silicon (Si): max 0.10%
  • Manganese (Mn): max 0.10%
  • Phosphorus (P): max 0.010%
  • Sulfur (S): max 0.008%
  • Chromium (Cr): 12.25% to 13.25%
  • Molybdenum (Mo): 2.00% to 2.50%
  • Nickel (Ni): 7.50% to 8.50%
  • Iron (Fe): balance

Applications

EN 3486:2019 steel X3CrNiMoAl13-8-2 (FE-PM67) is mainly used within the aerospace sector, where materials are required to withstand high stress, corrosion, and temperature variations while maintaining structural integrity. Typical applications include:

• High-Strength Aerospace Forgings: Critical components such as landing gear parts, structural airframe elements, and engine mounting brackets.

• Corrosion-Resistant Structural Parts: Components exposed to harsh environments requiring excellent oxidation and corrosion resistance.

• Precision Aircraft Parts: Applications demanding tight tolerances and superior mechanical performance with consistent material quality.

The standard ensures traceability, repeatability, and quality control vital for aerospace manufacturing, supporting safety-critical applications.

Related Standards

• EN 2157-3: Technical specifications for aerospace forging stock and forgings, detailing production and pre-production controls relevant to steel forgings.

• EN 3359: Specification for aerospace steel FE-PM1503, related to vacuum induction melted and consumable electrode remelted soft forgings, providing complementary material characteristics.

• EN 4258: General organization and linkage between metallic material standards for aerospace applications, supporting coherent standardization.

• EN 4500-005: Rules for drafting aerospace metallic material standards, ensuring uniform presentation and technical clarity in steel standards.

Conclusion

EN 3486:2019 provides comprehensive guidelines for manufacturing, testing, and certification of high-strength, solution annealed and precipitation hardened steel X3CrNiMoAl13-8-2 forgings up to 100 mm diameter specifically for aerospace use. This ensures aerospace manufacturers can rely on consistent mechanical properties and chemical composition essential for critical aerospace components. Adherence to this standard supports component performance, safety, and compliance within the aerospace industry's rigorous quality framework.
