Overview
SIST EN 3480:2025 is a European standard developed by CEN that specifies requirements for aerospace-grade steel X6CrNiTi18-10 (1.4541). This standard covers air melted, softened steel plates with thicknesses between 6 mm and 50 mm and tensile strengths ranging from 500 MPa to 700 MPa. The steel conforms to the W.nr 1.4541 designation and is identified by ASD-STAN as FE-PA3601. SIST EN 3480:2025 supersedes the 2007 edition, incorporating updates in material designation, testing formats, and bibliographic references.
This standard supports stringent aerospace industry demands for high-performance stainless steel plates, ensuring consistent mechanical properties, chemical composition, and quality for critical aerospace components.
Key Topics
Material Specification: Steel grade X6CrNiTi18-10 (1.4541) with controlled chemical composition:
- Chromium (Cr): 17.0% - 19.0%
- Nickel (Ni): 9.0% - 12.0%
- Carbon (C): max 0.08%
- Titanium (Ti): max 0.70%
- Other elements strictly limited to ensure corrosion resistance and weldability.
Physical Form: Rolled plates with thickness > 6 mm and ≤ 50 mm, delivered in a softened (annealed) condition.
Mechanical Properties:
- Tensile strength (Rm) between 500 MPa and 700 MPa
- Proof stress (Rp0.2) ≥ 200 MPa
- Elongation (A) ≥ 40%
- Hardness ≤ 207 HV
Quality Requirements:
- Maximum δ-ferrite content not exceeding 8%
- Grain size grade ≥ 4
- Inspection for inclusions, internal and external imperfections per EN 4700-001
- Visual and ultrasonic testing standards applied
Heat Treatment: Softening heat treatment between 1050 °C and 1100 °C (water quenching or air quenching/aging), ensuring appropriate microstructural properties.
Special Considerations:
- For high-power beam welding applications, tighter controls on sulfur, phosphorus, and boron content are recommended.
- Cr/Ni ratio adjustments according to the Suutala formula to optimize corrosion resistance.
Applications
The steel plates covered by SIST EN 3480:2025 are specifically designed for aerospace applications requiring reliable material performance under demanding environmental and mechanical conditions. Key applications include:
- Aircraft structural components where corrosion resistance and strength are vital
- Aerospace engine parts necessitating stable mechanical properties after heat treatment
- Components exposed to cyclic stresses and temperature variations
- High-integrity welded assemblies for airframes and aerospace systems
By adhering to this standard, manufacturers ensure material compatibility with aerospace quality programs, supporting enhanced safety, durability, and performance in aviation environments.
Related Standards
SIST EN 3480:2025 is part of a broader series of EN aerospace metallic material standards, harmonized under ASD-STAN and aligned with CEN regulations, including:
- EN 4258: General organization of aerospace metallic material standardization
- EN 4700-001: Technical specifications for wrought steel and heat-resisting alloy products (plate, sheet, strip)
- EN 4500-005: Rules for drafting material standards specific to aerospace steels
These interlinked standards ensure comprehensive guidance on material selection, testing methods, and documentation critical to aerospace manufacturing and certification processes.
By implementing SIST EN 3480:2025, aerospace industry stakeholders benefit from a harmonized specification that guarantees steel plate quality and performance, optimizing product development and regulatory compliance across European and international markets. Keywords such as aerospace steel plates, X6CrNiTi18-10 stainless steel, air melted, softened steel plates, and aerospace material standards highlight the document’s relevance in aerospace metallurgy and quality assurance.
