Overview

SIST EN 3489:2020 is a European standard developed by CEN and ASD-STAN for aerospace applications focusing on steel tubes used in structural components. It specifies the technical requirements for softened Steel X8CrNiTi18-10 (1.4878/1.4544) tubes with a tensile strength ranging from 500 to 750 MPa and wall thickness between 0.5 mm and 5 mm. This steel grade is an austenitic corrosion-resistant, weldable material commonly used in aircraft structures due to its strength and durability.

This standard ensures consistent quality and performance of steel tubes that are critical for aerospace structural integrity, safety, and longevity.

Key Topics

• Steel Grade: X8CrNiTi18-10 (also known as 1.4878/1.4544), an austenitic stainless steel with corrosion resistance.
• Mechanical Properties: Tensile strength (Rm) from 500 MPa to 750 MPa, elongation minimum 40% (or 35% depending on test method), and hardness not exceeding 207 HV.
• Physical Dimensions: Tubes with wall thickness (a) ranging from 0.5 mm to 5 mm.
• Delivery Condition: Softened state achieved by heat treatment between 1050°C and 1100°C with air or water quenching.
• Production Methods: Air melted seamless tubes ensuring uniform quality and properties.
• Testing and Inspection: Adheres to aerospace inspection and testing requirements as detailed in EN 2069-4.

---

Applications

SIST EN 3489:2020 steel tubes are crucial in aerospace structural applications where lightweight materials with high strength and corrosion resistance are required. Typical applications include:

• Structural tubing for aircraft frames and fuselage components
• High-performance aerospace assemblies where reliability and safety standards are critical
• Components exposed to corrosive environments requiring durable stainless steel
• Welded tubular structures in aerospace and defense industries

The standard supports manufacturers and engineers in selecting the appropriate steel tubes that meet stringent aerospace quality and performance criteria.
