Overview

EN 2476:2019 is a European Standard developed by CEN (European Committee for Standardization) that specifies the technical requirements for aerospace series steel 30CrNiMo8 (W.nr 1.6580). The standard covers forgings with a diameter (De) of up to 100 mm and a tensile strength (Rm) ranging between 1 100 MPa and 1 300 MPa. Originally prepared by ASD-STAN, this standard provides precise chemical composition limits, mechanical properties, and delivery conditions to ensure the material’s suitability for aerospace applications. EN 2476:2019 aligns with the aerospace industry's stringent demands for high-strength, durable steels used in critical components.

Key Topics

• Material Designation: Steel 30CrNiMo8 (1.6580), also recognized under ASD-STAN designation FE-PL74.
• Chemical Composition: Controlled ranges of carbon (0.26-0.34%), silicon, manganese, chromium, molybdenum, and nickel elements to maintain optimal performance.
• Mechanical Properties:
  • Tensile strength (Rm) between 1 100 MPa and 1 300 MPa.
  • Proof stress (Rp0.2) minimum 900 MPa for annealed condition, increasing to 1 030 MPa for hardened and tempered condition.
  • Elongation at break ≥ 9-10%.
  • Hardness values from HB ≤ 248 (annealed) up to HB 363-415 (hardened).
• Heat Treatment:
  • Delivery condition includes annealed or hardened and tempered states.
  • Typical heat treatment involves quenching between 840°C and 860°C, followed by tempering at temperatures of at least 560°C.
• Dimensions: Forgings covered have an external diameter (De) up to 100 mm.
• Testing and Inspection: Mechanical tests, hardness tests, and dimensional inspections are integral to validate compliance with the standard.
• Compliance: The standard must be adopted by CEN member countries as the national standard by June 2020, replacing any conflicting national standards.

Applications

EN 2476:2019 steel 30CrNiMo8 forgings are specifically designed for aerospace use due to their superior mechanical properties and reliability. Practical applications include:

• Structural aerospace components requiring high strength and toughness.
• Critical parts subjected to cyclic stressing and demanding environmental conditions.
• Components where dimensional fidelity and safe performance under stress are essential-such as gear parts, shafts, and landing gear components.
• Engineering parts in aircraft manufacturing where high tensile strength and resistance to fatigue are necessary.

This standard ensures that materials used in aerospace meet the agreed-upon specifications for safety, performance, and interchangeability in the highly regulated aerospace sector.

Summary

EN 2476:2019 is a critical standard for manufacturers and users of high-strength steel forgings in aerospace. It ensures that Steel 30CrNiMo8 forgings with diameters up to 100 mm meet strict mechanical and chemical requirements needed for aerospace safety and performance. By adhering to this standard, aerospace industries benefit from consistent quality, material reliability, and regulatory compliance.
