Overview
EN 2466:2009 is a CEN (ASD‑STAN) aerospace material standard that specifies requirements for Steel FE-PA3901 (X2CrNi19‑11) in the softened condition for forgings with De ≤ 100 mm. It forms part of the EN aerospace metallic materials series and establishes chemical limits, heat‑treatment/delivery conditions, mechanical properties and test/inspection links for use in aerospace applications.
Key topics and requirements
- Material designation: Steel FE‑PA3901 (X2CrNi19‑11) - an austenitic corrosion‑resisting steel (typical use stated in the standard).
- Chemical composition limits: C ≤ 0.030%; Si ≤ 1.00%; Mn ≤ 2.00%; P ≤ 0.035%; S ≤ 0.025%; Cr ≈ 17.0–19.0%; Ni ≈ 9.0–11.0% (Fe balance).
- Melting method: Air melted.
- Form and size: Forgings (forged from forging stock) with effective diameter De ≤ 100 mm.
- Delivery condition / heat treatment:Softened, heat treatment range 1 000 °C ≤ θ ≤ 1 050 °C with AQ or WQ (air or water quench). Reference treatment: softened + (1 040 ± 10) °C / WQ.
- Mechanical properties (softened condition):
- Proof stress Rp0.2 ≥ 180 MPa
- Tensile strength Rm = 450–650 MPa
- Elongation A ≥ 45%
- Hardness HB ≤ 187 (HV ≤ 196 for De ≤ 5 mm)
- Impact energy kV ≥ 100 J
- Testing & inspection: Test sample and inspection rules are referenced to EN 4700‑6 (pre‑production and production forgings) and general drafting rules EN 4500‑5. Product qualification program is to be agreed between manufacturer and purchaser.
Applications and users
- Practical applications: EN 2466:2009 is used where austenitic, corrosion‑resisting forged steel components in the softened condition are required within aerospace structures and systems. Typical use cases include forgings for parts that need good ductility, toughness and corrosion resistance while being produced by forging processes (De ≤ 100 mm).
- Who uses this standard: Material engineers, procurement/specification teams, aerospace forging manufacturers, quality and inspection departments, and certification bodies responsible for ensuring materials meet aerospace material system requirements.
