Overview
EN 3162:2025 is a CEN aerospace series standard (prepared by ASD‑STAN) that specifies material and inspection requirements for steel X5CrNiCu17‑4 (W.nr. 1.4542) in the form of sheets and strips (thickness a ≤ 6 mm) for aerospace use. Approved November 2025, it supersedes EN 3162:2007 and is designated by ASD‑STAN as FE‑PM3801. The standard covers air‑melted material delivered in solution treated or solution treated and precipitation treated conditions and sets minimum mechanical and metallurgical criteria including Rm ≥ 930 MPa.
Key topics and requirements
- Material designation: Steel X5CrNiCu17‑4 (1.4542), air melted.
- Forms covered: Sheets and strips, thickness a ≤ 6 mm.
- Delivery conditions: Solution treated (code W) and solution treated plus precipitation treated (code U).
- Heat treatment (as specified): Solution treatment at 1 025–1 055 °C / t ≤ 1 h with rapid cooling to ≤ 30 °C; precipitation treatment at 600–630 °C / t ≥ 4 h (where applicable).
- Mechanical properties: Proof stress Rp0.2 ≥ 725 MPa, tensile strength Rm ≥ 930 MPa, elongation A50 mm ≥ 8%.
- Hardness: Specified hardness ranges are given (HRC ~29–35; corresponding HV values shown in the standard).
- Microstructure and quality limits: δ‑ferrite content ≤ 5%, grain size G ≥ 4, inclusion category 2, visual testing for external imperfections.
- Testing and inspection: Test and test piece requirements reference EN 4700‑001 and δ‑ferrite measurement per EN 4436. Product qualification per EN 2043 is required and to be agreed between manufacturer and purchaser.
Applications and users
EN 3162:2025 targets aerospace material selection and procurement where a thin, high‑strength, corrosion‑resistant stainless steel is required. Typical practical uses include:
- Structural and secondary airframe components made from sheets and strips ≤ 6 mm
- High‑strength fasteners, fittings, or subcomponents requiring precipitation‑hardened properties
- Aerospace suppliers, material and process engineers, QA/QC inspectors, design engineers, and procurement teams specifying raw materials for certification and traceability
Users rely on this standard to ensure consistent mechanical performance, heat‑treatment control, and metallurgical quality for flight‑critical and non‑flight‑critical aerospace parts.
