Overview - EN 2573:2022 (Steel X6CrNiTi18-10 / 1.4541)

EN 2573:2022 is a CEN / ASD‑STAN aerospace standard that specifies requirements for wires made from Steel X6CrNiTi18‑10 (material number 1.4541). It covers air‑melted, softened, drawn wires with diameters in the range 0.25 mm ≤ D ≤ 3 mm and a maximum tensile strength of Rm ≤ 780 MPa. The ASD‑STAN designation for this product is FE‑PA3601. EN 2573:2022 supersedes EN 2573:2007 and is part of the EN aerospace metallic materials series.

Key topics and technical requirements

• Material designation: X6CrNiTi18‑10 (1.4541) - titanium‑stabilized chromium‑nickel steel (as identified by the standard designation).
• Form and production: Wires produced by drawing; air melted as the melting method.
• Size range: Diameter 0.25 mm to 3 mm (0,25 mm ≤ D ≤ 3 mm).
• Delivery condition: Softened (heat treated within specified range).
• Heat treatment: Typical heat treatment specified in the standard: 1050 °C to 1100 °C, followed by air cooling (AC) or water quench (WQ) as applicable.
• Mechanical properties: Tensile strength Rm ≤ 780 MPa; elongation A ≥ 40% (other mechanical test requirements and sampling follow EN 4700‑004).
• Testing and inspection: Test piece preparation, marking, dimensional inspection and product qualification are carried out according to EN 4700‑004; specific qualification programmes are agreed between manufacturer and purchaser.
• Typical use: The standard identifies locking wire as a typical application.

Practical applications and who uses this standard

• Aerospace manufacturers specifying corrosion‑resistant fastening and locking wire where controlled mechanical properties and traceability are required.
• Suppliers and wire producers who must meet CEN/ASD‑STAN acceptance, inspection and marking requirements for aerospace deliveries.
• Design and quality engineers responsible for material selection, procurement specifications, material certificates and qualification testing in aviation and defence projects.
• Maintenance, repair and overhaul (MRO) organizations using standardized locking wire and small‑diameter stainless steel wire for aircraft assemblies.

Using EN 2573:2022 helps ensure consistent material quality, reproducible mechanical performance, and compatibility with aerospace procurement and certification processes.

Related standards

• EN 4700‑004 - referenced for wire technical specification, test sample and inspection methods.
• EN 4258 - context for the EN aerospace metallic materials series and standard organization.
• EN 4500‑005 - drafting rules followed in preparation of this material standard.
