Overview
EN 4376:2016 is a CEN (European) aerospace material standard that specifies requirements for the heat‑resisting nickel‑based alloy NiCr19Fe19Nb5Mo3 (EN number 2.4668, also referenced as NI‑PH2601) in bar and section form with an outside diameter (De) ≤ 200 mm. The standard covers solution treated and solution + precipitation treated delivery conditions intended for aerospace applications and sets rules for chemical composition, production method, heat treatment, mechanical properties and inspection.
Key topics and requirements
- Material designation and chemistry: Alloy identified as NiCr19Fe19Nb5Mo3 (2.4668) with specified ranges for Ni, Cr, Fe, Nb, Mo and other elements (full composition tables are in the standard).
- Form and production: Covers wrought bars and sections with De ≤ 200 mm produced by consumable electrode remelting.
- Delivery conditions: Two main conditions - solution treated (code W) and solution + precipitation treated (code U). Heat‑treatment parameters and sequencing are defined; precipitation treatment commonly referenced at around 620 °C, with guidance that if furnace cooling rates fall outside specified ranges the precipitation time at 620 °C shall be increased (to ≥ 18 h).
- Mechanical and high‑temperature properties: Specifies proof stress (Rp0.2), tensile strength (Rm), elongation and rupture stress at ambient and elevated temperature (e.g., 650 °C). Example values are provided in the standard (e.g., Rp0.2 up to ~1 035 MPa; Rm up to ~1 270 MPa depending on condition).
- Microstructure and quality: Requirements for homogeneous microstructure, grain size limits, external/internal defect classification and allowable cladding thickness are referenced to EN 4700‑2.
- Testing and inspection: Testpiece orientation, hardness, bending and notch/unnotched rupture testing protocols are specified or cross‑referenced.
- Qualification and conformity: Product qualification and semi‑finished product qualification follow EN 2043 and general aerospace standard organization rules (EN 4258, EN 4500‑003).
