Overview

EN 4315 (prEN 4315:2024 / referenced as EN 4315:2025) is a CEN aerospace-series material standard that specifies requirements for the heat‑resisting nickel‑base alloy W.nr 1.4980 used in aerospace applications. The draft identifies the alloy as X4NiCrTiMoV26‑15 (W.nr 1.4980); the user-supplied title uses X6NiCrTiMoV26‑15 - verify the final normative designation in the published edition. The standard covers consumable-electrode remelted material in the form of bars and sections (rolled or extruded) with maximum cross-section a or D ≤ 100 mm and a minimum tensile strength Rm ≥ 900 MPa.

Key topics and requirements

  • Alloy and melting: High‑nickel, chromium‑titanium‑molybdenum‑vanadium heat‑resisting alloy, consumable electrode remelted for improved cleanliness and homogeneity. W.nr: 1.4980.
  • Forms and dimensions: Bars and sections produced by rolling or extrusion; limit dimension a or D ≤ 100 mm.
  • Heat treatments:
    • Solution treatment: 980 °C ± 10 °C, t ≥ 1 h, followed by oil or water quench (OQ/WQ).
    • Precipitation treatment (when required): 720 °C ± 10 °C, t ≥ 16 h / AC.
  • Mechanical properties (delivery/acceptance):
    • Tensile strength Rm ≥ 900 MPa
    • Proof stress Rp0.2 ≥ 590 MPa (where applicable)
    • Elongation A ≥ 13%, reduction of area ≥ 20%
    • Hardness: lower limits for solution treated and specified range for precipitation treated conditions per the table in the standard.
  • Testing and inspection:
    • Test pieces, sampling and mechanical tests per EN 4700‑002.
    • Non‑destructive testing: Ultrasonic testing (UT) Class 2 for internal imperfections; visual inspection (VT) for external imperfections.
    • Grain size requirement and optional macrostructure inspection to be agreed on order.
  • Qualification and delivery: Product qualification per EN 2043; technical specification and delivery conditions referenced to EN 4700‑002.

Applications and users

  • Intended for aerospace high‑temperature components where high tensile strength and heat resistance are required (e.g., structural or engine parts subject to elevated temperatures).
  • Primary users: materials engineers, procurement/specification writers, aerospace manufacturers, heat‑treatment and quality engineers, and suppliers of semi‑finished nickel‑base products who need compliance with aerospace material standards.
