Overview

EN 4377:2015 is a European Standard issued by CEN that specifies requirements for the heat resisting alloy NiCr19Fe19Nb5Mo3 (2.4668) in the form of non heat treated forging stock intended for aerospace applications. The standard covers material designation, production method, dimensional limits and required quality controls for forging stock with a or D ≤ 300 mm.

Key elements defined in the standard include the alloy chemical designation, melting method (consumable electrode remelted), form (forging stock), and delivery condition code U (non heat treated). EN 4377:2015 is part of the EN aerospace metallic materials series and links to the general organization and drafting rules in EN 4258 and EN 4500-003.

Key Topics

• Material designation: NiCr19Fe19Nb5Mo3 (2.4668) - heat resisting alloy for aerospace.
• Form and size limits: Forging stock; scope specifies a or D ≤ 300 mm (dimensions concerned are referenced within the standard).
• Melting and production: Consumable electrode remelted is specified as the method of melting.
• Delivery condition: Non heat treated (delivery condition code U).
• Reference heat treatment: The document also provides a reference solution and precipitation treatment sequence (specified temperature ranges and hold times) for qualification or post-processing when applicable.
• Quality and inspection: External/internal defect criteria, macrostructure, marking and dimensional inspection are referenced to prEN 2860-02 and EN 2043 for qualification and testing procedures.

Applications

EN 4377:2015 targets procurement, design and quality assurance activities for aerospace manufacturers, material suppliers and procurement teams working with high-temperature, heat resisting alloys. Practical applications include:

• Selecting forging stock for aerospace structural and engine components where high-temperature resistance is required.
• Specifying supplier acceptance criteria and inspection plans for delivered semi-finished forgings.
• Defining qualification and test programs in line with EN 2043 and prEN 2860-02 to ensure conformance to aerospace material expectations.

Benefits for users:

• Clear, harmonized material and delivery requirements for NiCr19Fe19Nb5Mo3 across CEN member states.
• Consistent reference to testing and inspection practices to support traceability and procurement.

Related Standards

• EN 2043 - General requirements for semi-finished product qualification (referenced for product qualification).
• prEN 2860-02 - Technical specification for forging stock and forgings (used for test pieces and inspection references).
• EN 4258 - Organization of the aerospace metallic materials series and links between standard types.
• EN 4500-003 - Rules for drafting and presentation specific to heat resisting alloys.

For procurement, certification and design use: consult EN 4377:2015 and the referenced documents to verify mechanical property tables, inspection rules and the qualification programme applicable to NiCr19Fe19Nb5Mo3 forging stock.
