Overview
This standard, EN 3971:2006 (CEN), defines requirements for Steel FE-PL1507 (40CrMoV12) supplied as forging stock for aerospace applications. It applies to material produced by the consumable electrode remelted method, delivered in the annealed condition, with section dimensions limited to a or D ≤ 350 mm. EN 3971:2006 is part of the aerospace series of metallic material standards and is intended to ensure consistent material quality, testing and traceability for critical aerospace components.
Key Topics
- Material designation and composition: Identifies FE-PL1507 (40CrMoV12) and specifies chemical composition limits and related notes on elements of concern.
- Method of melting: Requires consumable electrode remelting to achieve the specified metallurgical quality.
- Delivery condition: Material is supplied annealed; relevant delivery condition codes and heat-treatment reporting are covered.
- Form and dimensions: Applies to forging stock (form) with maximum section dimension a or D ≤ 350 mm.
- Inspection and tests: Mandates macro- and micrographic examinations, inclusion (micro‑cleanliness) assessment, dimensional and marking inspection, and other tests referenced in the standard.
- Product qualification: Product qualification and semi-finished product requirements are addressed; qualification programmes are to be agreed between manufacturer and purchaser.
- Quality controls: Emphasis on material integrity, internal/external defect limits, and traceability through inspection and test reports.
EN 3971:2006 also cross-references specific aerospace test and presentation rules so that material data, heat-treatment records and inspection outcomes are consistently recorded.
Applications
EN 3971:2006 is intended for aerospace and defence supply chains where reliable forging stock is required. Typical practical applications include:
- Production of forged aerospace components requiring controlled alloy chemistry and microstructure.
- Situations where high metallurgical cleanliness and documented heat-treatment history are essential.
- Use as a low-alloy general purpose steel suitable for subsequent surface treatments (the standard notes suitability for nitriding).
Benefits for users:
- Consistent material quality for flight-critical forgings.
- Traceability and testing aligned with aerospace procurement expectations.
- Reduced metallurgical variability through specified melting and inspection methods.
Related Standards
EN 3971:2006 references and links to several aerospace metallic-material standards and test methods, for example:
- EN 2002-8 - Micrographic determination of grain size
- EN 2003-7 - Macrographic test
- EN 2157-2 - Forging stock technical specification
- EN 2957 - Method of preparation of forged samples
- EN 2043 - General requirements for semi-finished product qualification
- EN 4258 - Organization of the aerospace metallic materials series
- EN 4500-5 - Rules for drafting and presentation of steel material standards
For procurement and engineering teams, EN 3971:2006 should be used together with the referenced test methods and with an agreed qualification programme between manufacturer and purchaser to ensure compliance with aerospace material expectations.
