Overview
SIST EN 4318:2026 is a European standard developed by CEN (European Committee for Standardization) under the aerospace series. This standard details the requirements for the heat-resisting alloy X6NiCrTiMoV26-15 (1.4980), specifically for consumable electrode remelted material that is both solution treated and precipitation treated. The scope applies to bars and sections with a diameter (De) up to 100 mm and a minimum tensile strength (Rm) of 960 MPa for aerospace applications. This document replaces the previous edition (EN 4318:2007) and aligns with evolving aerospace manufacturing and material qualification requirements.
Key Topics
Main subjects addressed in SIST EN 4318:2026 include:
- Material Specification: Definition and designation of heat-resisting alloy X6NiCrTiMoV26-15 (1.4980), also known under ASD-STAN designation FE-PA2601.
- Product Forms: Bars and sections with maximum diameter up to 100 mm.
- Metallurgical Processes: Requirement for consumable electrode remelting, with subsequent solution and precipitation treatment to achieve enhanced mechanical properties.
- Mechanical Properties: Emphasis on achieving high tensile strength (Rm ≥ 960 MPa) and specified minimum properties for elongation and reduction of area.
- Testing and Inspection: Visual and ultrasonic examinations, grain size requirements (G ≥ 3), and macrostructure specifications. Compliance with EN 4700-002 for test samples, pieces, and inspection methods.
- Qualification Requirements: Product qualification according to EN 2043, ensuring material reliability and consistent performance for critical aerospace applications.
Applications
SIST EN 4318:2026 is primarily targeted at the aerospace sector, where high-performance materials are essential for reliability and safety. Main application areas include:
- Aircraft Engine and Turbine Components: The heat-resisting properties and high mechanical strength make the alloy suitable for use in environments with elevated temperatures and strict mechanical demands.
- Structural Aerospace Parts: Bars and sections conforming to this standard are used in load-bearing and critical structural assemblies where performance under stress and at high temperature is required.
- Precision Machined Components: Thanks to controlled composition and robust properties, this material supports the production of complex aerospace parts with precise dimensional stability.
- Quality Assurance and Material Traceability: Stringent testing and marking requirements enable end-users and manufacturers to ensure traceability and compliance with aerospace quality systems.
