Overview

EN 2821:2024 specifies requirements for steel X5CrNiCu15-5 (1.4545) bars, which have undergone consumable electrode remelting, solution treatment, and precipitation treatment. The standard applies to bars for machining in aerospace applications, where the product dimensions are a or D ≤ 200 mm and the minimum tensile strength (Rm) is 1,310 MPa. Published by CEN, this updated standard supersedes EN 2821:2007 and supports the quality, consistency, and safety of critical metallic components within the aerospace sector.

Key Topics

• Steel Grade X5CrNiCu15-5 (1.4545):

  • Martensitic precipitation-hardened stainless steel
  • Suitable for high-strength, corrosion-resistant applications

• Manufacturing Requirements:

  • Consumable Electrode Remelted: Ensures high material purity and homogeneity
  • Solution Treated and Precipitation Treated: Provides the necessary mechanical properties and microstructure

• Product Form and Scope:

  • Bars for machining
  • Dimensions: a or D ≤ 200 mm
  • Minimum tensile strength: 1,310 MPa

• Mechanical Properties:

  • High strength-to-weight ratio
  • Minimum yield strength and hardness specifications

• Inspection and Testing:

  • Microstructure and grain size control
  • Non-metallic inclusion testing
  • Ultrasonic and visual inspection criteria

Applications

EN 2821:2024 is specifically tailored to the aerospace industry, supporting the production of steel bars used in machined components where reliability, structural integrity, and performance are paramount. Key application areas include:

• Aircraft Structural Components: Manufacturing of landing gear, actuators, and fasteners
• Engine Components: Shafts, disks, turbine parts requiring high strength and corrosion resistance
• Spacecraft Structures: Satellite elements and other aerospace frameworks exposed to demanding environments
• Precision Machined Parts: Any aerospace part where tight tolerances and certified mechanical properties are essential

Utilizing consumable electrode remelted X5CrNiCu15-5 bars ensures enhanced material cleanliness, mechanical consistency, and improved fatigue resistance - all critical to meeting rigorous aerospace standards.
