Overview

SIST EN 3488:2024 is a European standard developed by CEN, specifying the requirements for Steel X6CrNiTi18-10 (1.4541) in aerospace applications. This steel grade is air melted, softened, and supplied as sheets and strips with a thickness up to 6 mm. It targets mechanical properties with tensile strength (Rm) between 500 MPa and 700 MPa, meeting critical performance characteristics required in the aerospace industry. The standard replaces the previous EN 3488:2007 edition, incorporating editorial improvements and updated references.

Key Topics

• Material Specification: Steel X6CrNiTi18-10 (1.4541), also referenced as W. Nr 1.4541 and ASD-STAN designation FE-PA3601.
• Production Method: Air melting process followed by softening heat treatment within 1050 °C to 1100 °C, supplied as rolled sheets and strips.
• Dimensions: Applicable for thickness ≤ 6 mm, with dimensional and mechanical criteria strictly defined.
• Mechanical Properties:
  • Tensile strength (Rm): 500 - 700 MPa
  • Proof stress (Rp0.2): ≥ 220 MPa
  • Elongation (A%): ≥ 40%
  • Hardness (HB): ≤ 207
• Chemical Composition:
  • Chromium: 17.0% - 19.0%
  • Nickel: 9.0% - 12.0%
  • Titanium: Around 5 times carbon content
  • Limits on carbon, silicon, manganese, phosphorus, sulfur, and titanium ensure material integrity.
• Microstructural Requirements: Ferrite content capped at 8%, grain size minimum of 5 according to EN 4700-001 to guarantee performance consistency.
• Quality Assurance: Compliance with visual inspection, inclusion content category 2, and other standardized tests for aerospace-grade steel.
• Delivery Condition: Material supplied softened, ensuring optimal formability and performance.

Applications

SIST EN 3488:2024 steel sheets and strips are primarily designed for aerospace structural components that demand lightweight, corrosion-resistant, and high-strength materials. Typical uses include:

• Aircraft skin panels
• Structural reinforcements and frames
• Aerospace mechanical components requiring precise mechanical property control
• Manufacturing of parts where reliability and safety are paramount due to material consistency and traceability ensured by this standard

The air melted and softened nature of the material ensures excellent weldability and machining characteristics vital for aerospace manufacturing processes.

Related Standards

• EN 4700-001: Technical specification for wrought aerospace steels and heat-resisting alloys, detailing forms, testing, and delivery conditions.
• EN 2951: Focus on micrographic determination of non-metallic inclusions to ensure cleanliness of metallic aerospace materials.
• EN 4436: Methods for steel ferrite content measurement critical for assessing microstructure in aerospace steel products.
• EN 4258: General organization of aerospace metallic materials standardization series, providing context for EN 3488’s structure and use.
• EN 4500-005: Specific rules for drafting steel material standards in aerospace series.

Practical Value

Adopting SIST EN 3488:2024 enables aerospace manufacturers to standardize on a high-quality stainless steel grade with well-defined mechanical and compositional properties. This facilitates consistent performance in demanding applications, reduces risk associated with material variability, and improves supply chain management through compliance with widely accepted European aerospace standards. Furthermore, nickel-chromium-titanium stabilized steel in softened condition offers a balanced combination of strength, corrosion resistance, and formability, making it indispensable for advanced aerospace engineering.
