Overview
EN 4468:2007 is a European standard published by CEN that defines the technical requirements for steel FE-PM1505 (X1CrNiMoAlTi12-9-2) intended for aerospace applications. This specific steel grade is vacuum induction melted and consumable electrode remelted, ensuring superior purity and homogeneity. The standard covers bars with diameters or thicknesses (a or D) up to 150 mm, subjected to solution treatment and precipitation treatment to achieve high mechanical performance.
Key features of this aerospace steel include a minimum tensile strength (Rm) of 1300 MPa, making it suitable for critical structural components in the aerospace industry where high strength-to-weight ratio and reliability are essential.
Key Topics
Material Composition:
The standard specifies a strict chemical composition with key alloying elements including Chromium (11.5 - 12.5%), Molybdenum (1.85 - 2.15%), Nickel (8.5 - 9.5%), Aluminum (0.6 - 0.8%), Titanium (0.28 - 0.37%), and Nitrogen (up to 0.010%). Carbon, Silicon, Manganese, Phosphorus, and Sulfur are tightly controlled to optimize mechanical properties and corrosion resistance.Melting and Remelting Processes:
The steel is produced using vacuum induction melting followed by consumable electrode remelting, a process that improves cleanliness and reduces inclusions, key for aerospace-grade materials.Heat Treatments:
The bars undergo solution treatment at 820-860 °C followed by cooling to ≤ 20 °C, and precipitation treatment between 525-545 °C for at least 4 hours to enhance strength and toughness.Mechanical Properties:
- Minimum tensile strength (Rm) ≥ 1300 MPa
- Proof stress (Rp0.2) ≥ 1200 MPa
- Elongation ≥ 9-11%
- Reduction of area ≥ 45-50%
- Hardness ≤ 363 HB in the solution treated state and ≥ 380 HB after precipitation treatment
- Impact strength requirements ensure material toughness at various notch directions and temperatures.
Dimensional and Testing Requirements:
Bars are limited to a maximum diameter or thickness of 150 mm. Testing includes ferrite content, microstructure, grain size, and cleanliness to guarantee conformity with aerospace standards.
Applications
EN 4468:2007 steel FE-PM1505 is specifically tailored for demanding aerospace applications, such as:
- Structural components requiring very high strength and excellent fatigue resistance
- Aircraft engine parts that must maintain toughness and strength under extreme temperatures and stresses
- High-performance bars used in aerospace manufacturing where dimensional precision and material reliability are critical
This standard ensures that manufacturers and purchasers adhere to rigorous quality criteria, resulting in safer, reliable aerospace materials optimized for performance.
