Overview
SIST EN 4314:2026 is a European standard developed by CEN, focusing on requirements for the aerospace-grade, heat-resisting alloy X4NiCrTiMoV26-15 (1.4680). This standard specifies the properties and supply conditions for forging stock that is consumable electrode remelted and not heat treated, with a cross-section (a or D) ≤ 250 mm. The material and process covered are critical for high-performance, safety-driven aerospace applications where consistent quality is paramount. SIST EN 4314:2026 supersedes the 2007 version and aligns with the ASD-STAN designation FE-PA2602.
Key Topics
- Material Specification
- Alloy: Heat-resisting X4NiCrTiMoV26-15 (1.4680)
- Products: Forging stock
- Cross-section limits: a or D ≤ 250 mm
- Production Method
- Consumable electrode remelting process for superior homogeneity and purity.
- Delivery Condition
- Delivered not heat treated, allowing end-users to apply appropriate treatments based on specific aerospace component requirements.
- Dimensional and Quality Assurance
- Strict requirements for internal and external imperfection assessment, including visual and ultrasonic testing.
- Conformance to EN 4700-005 for technical and dimensional specifications.
- Qualification and Marking
- Product and manufacturer qualification in accordance with EN 2043.
- Clear marking and traceability practices.
Applications
SIST EN 4314:2026 is tailored for the aerospace industry, specifically for the supply of forging stock used in critical components, such as:
- Aero engine parts: Where resistance to high temperatures and mechanical stresses is essential.
- Structural aerospace components: Ensuring reliability and durability in extreme environments.
- Aerospace fasteners and fittings: Where material homogeneity and consistent mechanical properties are necessary.
- Custom aerospace forgings: For further processing into finished parts with demanding criteria for temperature, stress, and fatigue life.
The specification of not heat-treated stock allows aerospace manufacturers and suppliers to apply tailored heat treatments aligned with design and performance needs, enhancing material performance for targeted applications.
