Overview

EN 2465:2019 is a CEN aerospace-series standard that specifies requirements for steel X2CrNi18-9 (1.4307) supplied in a softened condition as bars for machining with nominal diameters 4 mm ≤ De ≤ 100 mm. The standard targets aerospace applications and defines chemical composition, delivery condition, heat treatment, mechanical properties and inspection/qualification rules for this stainless steel grade. EN 2465:2019 supersedes EN 2465:2007 and is prepared in line with ASD‑STAN and CEN procedures.

Key Topics and Requirements

  • Material designation: Steel X2CrNi18-9 (1.4307).
  • Chemical composition (typical limits):
    • C ≤ 0.030 %, Si ≤ 1.0 %, Mn ≤ 2.0 %, S ≤ 0.015 %, P ≤ 0.035 %
    • Cr: 17.5 % – 19.5 %, Ni: 9.0 % – 10.5 %, N ≤ 0.10 %
  • Melting method: Air melted.
  • Form and sizes: Bars for machining; diameter range 4 mm ≤ De ≤ 100 mm.
  • Delivery condition: Softened (code U). Heat treatment: 1 000 °C ≤ θ ≤ 1 100 °C followed by AC or WQ (as specified in the standard).
  • Mechanical properties:
    • Tensile strength Rm: 450 MPa ≤ Rm ≤ 680 MPa
    • Proof stress Rp0.2: ≥ 180 MPa for 4 ≤ De ≤ 50 mm; ≥ 170 MPa for 50 < De ≤ 100 mm
    • Elongation A: ≥ 45 %
    • Hardness HB: ≤ 200
  • Inclusion and cleanliness: Assessed by EN 4700‑002 referencing ASTM E45 (Method A); inclusion types A–D with defined acceptance levels.
  • Production & testing: Manufacturing and inspection follow EN 4700‑002 (bar and section technical specification) and related aerospace material drafting rules.
  • Notes and options by agreement: Reduced S/P limits for special welding applications, alternative Ni content up to 9 % by agreement, and adjusted hardness/tensile/elongation limits for certain cold-deformed or hot-formed sections.

Applications and Who Uses It

EN 2465:2019 is used by:

  • Aerospace manufacturers and OEMs specifying raw material for machined components
  • Materials engineers and metallurgists verifying compliance for procurement
  • Bar and rod suppliers producing aerospace-grade stainless steel
  • Quality, inspection and testing laboratories performing mechanical and metallurgical verification

Typical application scope: supply and specification of machined bar stock for aerospace components where this stainless steel grade and the defined mechanical/chemical envelope are required.
