Overview
SIST EN 2480:2026 is a European standard developed by CEN for aerospace-grade steel bars, specifically focusing on Steel 36NiCrMo16 (1.6773), also designated as FE-PL2108 under ASD-STAN. This standard applies to bars with a diameter of up to 75 mm and a tensile strength (Rm) range between 1,250 MPa and 1,400 MPa, making it ideal for high-performance aerospace applications. The document supersedes EN 2480:2008 and integrates significant updates to improve compliance with current aerospace metallurgical and dimensional standards.
Key Topics
Material Specifications
SIST EN 2480:2026 specifies the chemical composition limits for Steel 36NiCrMo16, ensuring optimal balance of elements like Carbon, Silicon, Manganese, Chromium, Molybdenum, and Nickel to achieve the desired mechanical properties.Mechanical Properties
The standard mandates rigorous mechanical property requirements including:- Tensile strength (Rm) between 1,250 MPa to 1,400 MPa
- Minimum elongation of 8%
- Reduction of area minimum 40%
- Impact strength (KV) not less than 25 Joules
- Hardness ranges specified in HB or HV depending on bar diameter
Dimensions and Form
Bars covered in this standard must have an external diameter (De) of 75 mm or less, ensuring suitability for aerospace components requiring precise size control.Heat Treatment and Delivery Conditions
Steel bars are delivered in a hardened and tempered condition, treated at temperatures ranging between 860 °C and 880 °C followed by a tempering temperature not lower than 540 °C, guaranteeing consistent mechanical performance.Quality Inspections
The standard also prescribes comprehensive testing protocols such as:- Visual testing for surface imperfections
- Ultrasonic testing for internal flaws
- Verification of non-metallic inclusion content according to EN 2951
- Dimensional verification aligned with EN 4700-002 and TR 2410
Additional Requirements
SIST EN 2480:2026 includes guidelines for product qualification programs mutually agreed upon by manufacturers and purchasers to maintain quality assurance.
Applications
Steel 36NiCrMo16 bars conforming to SIST EN 2480:2026 are tailored for aerospace industry uses where high strength-to-weight ratio, toughness, and reliability are critical. Typical applications include:
- Structural aerospace components
- Landing gear parts
- Engine shafts and mechanical assemblies
- High-stress load-bearing aerospace hardware
- Precision machined components requiring dimensional stability and predictable mechanical behavior under extreme conditions
The standard ensures that the steel bars provide consistent mechanical properties, chemical composition, and quality control needed for safety-critical aerospace structures.
