Overview
EN 3357:2019 is a CEN (ASD-STAN) aerospace series standard that defines material and product requirements for steel FE‑PM1503 (X3CrNiMoAl 13‑8‑2) supplied as bars for machining (a or D ≤ 150 mm). The standard covers permitted chemical composition, melting and remelting methods, specified heat treatments (solution treated and precipitation treated), mechanical properties (notably tensile strength 1 200–1 400 MPa), hardness, microstructure and inspection/qualification requirements for aerospace applications.
Key topics and technical requirements
- Material designation: FE‑PM1503 (X3CrNiMoAl 13‑8‑2) with specified element limits (e.g., Cr ≈ 12.25–13.25%, Mo 2.0–2.5%, Ni 7.5–8.5%, Al 0.90–1.35%, C ≤ 0.05%, N ≤ 0.010%).
- Melting/remelting: Vacuum induction melted and consumable electrode remelted to ensure clean metallurgy.
- Form & size: Bars for machining with cross‑section a or D ≤ 150 mm.
- Heat treatment: Solution treatment at 900–950 °C (t ≥ 30 min) followed by cooling to ≤ 15 °C; optional precipitation (aging) at 545–575 °C for 4 h (air cooling) - delivery condition codes W (solution) and U (solution + ageing).
- Mechanical properties:
- Tensile strength Rm = 1 200–1 400 MPa
- Proof stress Rp0.2 ≥ 1 140 MPa (where applicable)
- Elongation A ≥ 10%
- Reduction of area Z ≥ 45–50% depending on section
- Hardness limits: ≤ 363 HB or HRC 38–43
- Impact requirements: KV ≥ 40 J (T‑notch) and KV ≥ 20 J (L‑notch) at specified orientations
- Microstructure & cleanliness: δ‑ferrite content ≤ 2%; grain size and micro‑cleanliness categories specified; macrostructure and inclusion classes referenced.
- Testing & inspection: References included to EN 4700‑002 (bar specification), EN 2003‑7 (macrographic test), EN 4050‑1 (ultrasonic inspection), EN 4436 (delta ferrite), and EN 2043 (product qualification).
Applications and who uses this standard
- Intended for critical aerospace components requiring high‑strength, corrosion‑resistant, precipitation‑hardenable stainless steel bars (e.g., landing gear subcomponents, actuation parts, high‑load fasteners after machining).
- Primary users:
- Aerospace OEMs and structural engineers specifying materials
- Material suppliers and steel mills producing FE‑PM1503 bars
- Heat‑treat and machining vendors
- Quality, inspection and procurement teams managing material acceptance and qualification
Related standards
- EN 4700‑002 - Bar and section technical spec (wrought products)
- EN 2003‑7 - Macrographic test for steels
- EN 4050‑1 - Ultrasonic inspection of bars and forgings
- EN 4436 - Determination of delta ferrite content
- EN 2043 - Semi‑finished product qualification
EN 3357:2019 ensures consistent production, inspection and delivery of FE‑PM1503 bars for high‑performance aerospace applications - key for traceability, procurement and manufacturing quality control.
