Overview
SIST EN 3480:2025 is a European Standard developed by CEN for the aerospace sector, focusing on steel grade X6CrNiTi18-10 (material number 1.4541). This standard defines requirements for air melted, softened plates with thicknesses between 6 mm and 50 mm, and ultimate tensile strength (Rm) between 500 MPa and 700 MPa. The specification ensures that the material meets stringent manufacturing and quality control criteria suitable for demanding aerospace applications. The ASD-STAN designation for this steel is FE-PA3601.
Key Topics
- Material designation: Steel X6CrNiTi18-10 (1.4541), a titanium-stabilized austenitic stainless steel.
- Product form: Plates, rolled and softened by heat treatment.
- Thickness range: Greater than 6 mm and up to 50 mm.
- Mechanical properties: Ultimate tensile strength (Rm) 500 MPa to 700 MPa; minimum proof stress (Rp0.2) of 200 MPa; minimum elongation of 40%.
- Heat treatment: Plates delivered in the softened condition at 1050°C to 1100°C, followed by water or air quenching.
- Testing and quality control: Requirements cover chemical composition, mechanical testing, microstructure evaluation, grain size, inclusion and imperfection limits, intergranular corrosion resistance, and mandatory product marking and inspection according to EN 4700-001.
- Weldability: For specialized applications, adjustments to impurity levels and chemical ratios may be agreed upon by manufacturer and purchaser.
Applications
- Aerospace structures: Used for manufacturing load-bearing components, fuselage panels, and structural supports requiring corrosion resistance and high mechanical strength.
- Engine components: Suitable for non-critical engine plates and mounting brackets exposed to moderate temperatures and stresses.
- General fabrication: Ideal for parts that require good weldability and mechanical performance in aerospace and potentially other regulated industries.
- Special environments: The material’s resistance to intergranular corrosion and inclusions makes it appropriate for components exposed to aggressive atmospheres or thermal cycles.
The focus on the 1.4541 steel plate's properties - notably its robust alloying and balanced mechanical performance - ensures reliable performance in high-stress and safety-critical situations typical of aerospace environments.
Related Standards
- EN 4700-001: Technical specifications for wrought steel and heat-resisting alloy products in aerospace applications, referenced for testing and quality inspection.
- EN 4258: Provides a general framework for the organization and application of metallic material standards in the aerospace series.
- EN 4500-005: Sets out specific rules for drafting and presenting steel material standards, ensuring consistency and clarity across documents.
Other standards in the EN metallic materials series may also be relevant for downstream processing, fabrication, or certification within the aerospace field.
