Overview

EN 3160:2007 is a CEN aerospace material standard that specifies requirements for high-strength stainless-type steel FE-PM3801 (X5CrNiCu17-4) supplied as bars (a or D ≤ 200 mm) that are air melted, solution treated and precipitation treated for aerospace use. The standard sets chemical composition limits, heat treatment regimes, mechanical property minima and acceptance criteria appropriate to critical aerospace semi‑finished products. It is part of the EN aerospace metallic materials series and is intended for suppliers, purchasers and quality laboratories in the aerospace sector.

Key topics and requirements

  • Material designation: FE‑PM3801 (X5CrNiCu17‑4) - air melted.
  • Form and size: Bar form, maximum cross dimension or diameter ≤ 200 mm.
  • Chemical composition limits (examples given in the standard): C ≤ 0.07%, Si ≤ 1.00%, Mn ≤ 1.00%, P ≤ 0.040%, S ≤ 0.030%, Cr ≈ 15–17.5%, Mo ≤ 0.50%, Ni ≤ 5.0%, Cu ≤ 5.0%, Nb+Ta ≤ 0.45%.
  • Heat treatment: Solution treatment 1 025–1 055 °C for ≥ 30 min with air or oil quench to ≤ 30 °C; precipitation ageing 470–490 °C for ≥ 1 h (where required) followed by air cooling.
  • Mechanical properties:Tensile strength Rm ≥ 1 310 MPa and proof stress Rp0.2 ≥ 1 170 MPa (with diameter-dependent elongation and hardness limits described in the standard).
  • Microstructure and quality: δ‑ferrite content ≤ 5%, grain size G ≥ 4, inclusion/cleanliness Category 2, internal defects Class 2. Specific inspection, test-piece and sampling rules follow EN 4700‑2.
  • Delivery and test rules: Delivery conditions, test pieces, dimensional, marking and acceptance inspections are aligned with EN 4700‑2 and EN 2043.

Applications and users

  • Intended for aerospace manufacturers, material suppliers, procurement and quality teams, and testing laboratories.
  • Typical uses include aerospace structural and mechanical components requiring very high tensile strength in bar form where controlled heat treatment and material cleanliness are essential.
  • Useful in procurement specifications, qualifying suppliers and confirming compliance for critical semi‑finished components in aircraft and aerospace systems.
