Overview
EN 3532:2025 is a CEN (ASD‑STAN) aerospace material standard that specifies requirements for steel X2NiCoMo18‑8‑5 (W.nr. 1.6359 / ASD‑STAN FE‑PM2701) in plate form. The standard covers vacuum induction melted (VIM) and vacuum arc remelted (VAR), rolled plates with thickness in the range 6 mm < a ≤ 40 mm, supplied solution treated and precipitation treated for aerospace use. Target mechanical strength is Rm = 1 750–2 000 MPa with a proof stress ≥ 1 650 MPa and specified toughness and hardness limits.
Key topics and technical requirements
- Material designation: Steel X2NiCoMo18‑8‑5 (1.6359).
- Melting and production: Vacuum induction melted and vacuum arc remelted; rolled plates.
- Dimensions: Applicable plate thickness 6 mm < a ≤ 40 mm.
- Heat treatments:
- Delivery (solution treated): 790 °C ≤ θ ≤ 840 °C / air cool
- Use condition (solution + precipitation treated): 465 °C ≤ θ ≤ 495 °C / t ≥ 3 h / air cool
- Mechanical properties:
- Tensile strength Rm: 1 750 ≤ Rm ≤ 2 000 MPa
- Proof stress Rp0.2: ≥ 1 650 MPa (for specified thickness ranges)
- Elongation A: ≥ 5%
- Impact: KV ≥ 15 J (notch in T direction)
- Hardness: specified range for the applicable thickness (see standard table)
- Quality and inspection: Visual testing (VT), ultrasonic testing (UT), inclusion content (EN 2951) - Category 5, grain size G ≥ 6 (occasional G ≥ 4 allowed), marking and dimensional inspection per EN 4700‑001.
- Product qualification: Agreement between manufacturer and purchaser in accordance with EN 2043.
Practical applications
EN 3532:2025 is intended for aerospace components and assemblies requiring very high-strength, vacuum‑remelted steel plates where controlled chemistry, toughness and high tensile strength are critical. Typical uses include structural aerospace parts, high‑stress fittings, and engineered components where traceability, material consistency and aerospace specification compliance are required.
Who uses this standard
- Aerospace materials engineers and metallurgists selecting high‑strength steels.
- Procurement and specification writers in aerospace OEMs and Tier‑1 suppliers.
- Manufacturers of rolled plates and precision components requiring VIM/VAR material.
- Test laboratories and quality assurance teams performing acceptance testing and product qualification.
- Certification authorities and design offices referencing material standards in product approvals.
