Overview

EN 2402:2014 is a CEN aerospace series standard specifying requirements for the heat‑resisting nickel base alloy NiCr20Co3Fe3 supplied as annealed wire with diameter D ≤ 10 mm. Prepared under ASD‑STAN and adopted by CEN, the standard focuses on material designation, delivery condition, production method and the mandatory consideration of chemical composition for aerospace applications.

This standard is part of the EN metallic materials for aerospace series and is intended to ensure consistent material quality, traceability and suitability for high‑temperature aerospace components.

Key Topics

• Material designation: Heat resisting nickel base alloy NiCr20Co3Fe3 (only the chemical composition is to be considered for this designation).
• Form and production: Wire form produced by cold drawing.
• Limit dimensions: Wire diameter D ≤ 10 mm.
• Melting methods: Acceptable melting routes include air or vacuum melting, air melted then vacuum refined, or consumable electrode remelted.
• Delivery condition: Annealed and descaled or bright annealed; specified heat treatment range is 1 000 °C to 1 050 °C with air cooling or cooling in protective atmosphere.
• Referenced test and qualification standards: Normative references include EN 4700-004 (wire technical specification), EN 3238 (shear test for wires), and EN 2043 (semi‑finished product qualification).

Applications

EN 2402:2014 is tailored for aerospace industry stakeholders who require reliable, heat‑resisting nickel alloy wire for high‑temperature or corrosion‑resistant parts. Typical practical benefits include:

• Material consistency: Standardized chemical composition requirements reduce variability across suppliers.
• Quality assurance: Defined delivery conditions and referenced test methods support purchaser verification and batch acceptance.
• Traceability and procurement: Clear designation and normative links to EN product qualification streamline procurement and certification processes for aerospace components.

Use cases include feedstock for manufacturing small diameter high‑temperature components, fasteners or wire‑formed parts where NiCr20Co3Fe3 alloy properties are required and where D ≤ 10 mm is a dimensional constraint.

Related Standards

• EN 4700-004: Technical specification for wire-provides details on sampling, tests and tolerances for wrought heat‑resisting alloys.
• EN 3238: Test method for shear testing of wires and rivets-used for shear strength verification.
• EN 2043: General requirements for semi‑finished product qualification-outlines product qualification programme and supplier/purchaser agreement.

For procurement, qualification and engineering use, reference EN 2402:2014 alongside these normative documents to ensure full compliance with aerospace material requirements and testing protocols.
