Overview - EN 3018:2019 (Aerospace series)

EN 3018:2019 is a CEN (European) material standard that defines requirements for the heat‑resisting alloy NI‑PH2801 (NiCr16Fe7Ti3Nb1Al1) supplied as consumable‑electrode remelted, cold‑drawn wire for the manufacture of thread inserts with diameter D ≤ 3 mm for aerospace use. It forms part of the aerospace metallic materials series and prescribes composition, production, delivery condition, mechanical performance and inspection criteria for high‑temperature, nickel‑base wire used in critical fastening applications.

Key topics and requirements

• Material designation: NI‑PH2801 (NiCr16Fe7Ti3Nb1Al1), a nickel‑base, heat‑resisting alloy.
• Chemical composition: The standard specifies element limits. Representative ranges (see EN 3018:2019 table) include:
  • Cr 14.0–17.0%, Fe 5.0–9.0%, Nb (+Ta) 0.70–1.20%, Ti 2.25–2.75%, Al 0.40–1.00%, Cu ≤0.50%; Ni as balance.
  • Carbon, silicon, manganese and trace impurities are controlled (e.g., C ≤0.08%, Si ≤0.50%, Mn ≤1.00%, P ≤0.015%, S ≤0.010%, Co ≤1.00%).
• Manufacture: Consumable electrode remelted melting method; cold drawn wire form; limit diameter D ≤ 3 mm.
• Delivery condition: Code U (cold drawn). A specified use condition heat treatment is +700 °C ±5 °C for ≥4 h followed by air cooling (AC).
• Mechanical performance: Minimum tensile strength (Rm) thresholds are defined - for example ≥900 MPa in the delivery condition and ≥1 240 MPa after the +700 °C use condition (see standard for complete test protocols).
• Inspection and tests: Dimensional checks, visual external defect inspection (refer EN 3235‑5), wrapping test (5 turns on mandrel = wire diameter; no cracks), and sampling/testpiece rules per EN 3235‑5. Product qualification follows EN 2043.

Applications and users

• Primary use: Wire feedstock for manufacturing thread inserts and related fastener components where elevated temperature resistance is critical (aerospace engines, hot structures, exhaust systems, and high‑temperature fastened joints).
• Who uses this standard: Aerospace materials engineers, procurement/specification writers, fastener and insert manufacturers, metallurgists, quality and inspection teams, and testing laboratories involved with aerospace component qualification.

Related standards

• EN 3235‑5 - Technical specification for wire (wrought products) of heat‑resisting alloys
• EN 2043 - General requirements for semi‑finished product qualification
• EN 4258 / EN 4500‑003 - Organization and drafting rules for aerospace metallic material standards

EN 3018:2019 provides a precise, auditable specification for high‑temperature nickel‑base wire used in aerospace thread inserts - essential for consistent material performance, procurement and component qualification.
