Overview
SIST EN 2480:2026 is a European standard developed by CEN for the aerospace sector, detailing the requirements for steel bars made from 36NiCrMo16 (1.6773) with a tensile strength range of 1 250 MPa to 1 400 MPa and a nominal diameter of up to 75 mm. Known for its high strength and excellent mechanical properties, this low alloy steel is widely used in demanding aerospace applications, where reliability and quality are critical.
This standard supersedes EN 2480:2008, introducing editorial updates and aligning with current industry needs. SIST EN 2480:2026 is applicable to forged or rolled steel bars, ensuring consistent product quality across the European aerospace supply chain.
Key Topics
- Material Requirements: Specifies chemical composition and mechanical properties for FE-PL2108 (36NiCrMo16) steel, focused on ensuring high performance and safety.
- Product Forms: Applies to round bars with a diameter (De) not exceeding 75 mm, a common dimension for aerospace mechanical components.
- Heat Treatment and Delivery Conditions: Outlines requirements for annealed, hardened, and tempered conditions, ensuring desired strength and resilience.
- Testing and Inspection: Consistency is guaranteed through:
- Micrographic inclusion content (EN 2951)
- Ultrasonic and visual inspections (EN 4700-002)
- Hardness, tensile, and impact strength tests
- Marking and Traceability: Ensures full identification and traceability of each batch for quality assurance and regulatory compliance.
Applications
SIST EN 2480:2026 is pivotal in the aerospace industry, where high-strength alloy steel bars are essential for components subjected to extreme mechanical stresses. Typical applications include:
- Aircraft Engine Parts: Shafts, bolts, and gears requiring precise mechanical strength and fatigue resistance.
- Landing Gear Components: Where impact and shear strength are vital.
- Structural Elements: Airframe parts where a balance of toughness and light weight is crucial.
- General Aerospace Mechanical Parts: Any application within aerospace assemblies where certified, high-spec bars are necessary for performance and safety.
Because the standard strictly defines mechanical and metallurgical properties, it is also a reference point for suppliers and manufacturers producing or purchasing aerospace-grade steel bars to meet contractual and regulatory requirements.
Related Standards
Users of SIST EN 2480:2026 will often reference related European standards to ensure holistic quality compliance:
- EN 2951: Aerospace series – Determination of non-metallic inclusions in metallic materials, critical for assessing material cleanliness.
- EN 4700-002: Technical specification for steel and heat resisting alloy wrought products in aerospace applications.
- EN 4258: Organization of standardization and the relationship between dimensional and material standards in aerospace.
- EN 2034 / EN 2042: Standardized tolerances and dimensions for round and square steel bars, respectively.
- TR 2410: Guidance on the relationship between dimensional standards and material standards for metallic aerospace materials.
By adopting SIST EN 2480:2026, organizations align their production, procurement, and quality assurance processes with recognized aerospace material standards. This facilitates market access, improves cross-border supply chain collaboration, and ensures compliance with regulatory and safety requirements in Europe and globally.
