Overview

EN 4883:2022 is a European standard developed by CEN that defines the requirements for Steel X5CrNiCu 17-4 (1.4542) in aerospace applications. This high-strength steel grade is air melted, solution treated, and precipitation treated, provided in the form of plates with thicknesses ranging from 6 mm to 100 mm. The standard ensures a minimum tensile strength (Rm) of 1,070 MPa, making it suitable for critical aerospace components that demand superior mechanical performance and reliability.

This standard forms part of the aerospace series of metallic material standards prepared by ASD-STAN, focusing specifically on materials optimally processed for aerospace engineering.

Key Topics

• Material Specification
  Specifies chemical composition limits, including elements like Carbon (C), Silicon (Si), Manganese (Mn), Chromium (Cr), Nickel (Ni), Copper (Cu), and Niobium + Tantalum (Nb + Ta), all critical for achieving the required mechanical and corrosion resistance properties.

• Processing Requirements
  The steel must be produced via air melting followed by solution treatment (at temperatures between 1025 °C and 1055 °C for 30 minutes minimum) and precipitation hardening (540 °C to 560 °C for at least 4 hours). These treatments ensure the steel attains high strength and stability.

• Mechanical Properties
  Minimum tensile strength of 1,070 MPa and proof stress above 1,000 MPa are mandatory. Ductility requirements include elongation over 7% and reduction of area above 27% in the use condition. Hardness values range between 331 HBW and 401 HBW, depending on thickness and heat treatment condition.

• Testing and Quality Control
  Compliance involves visual inspections (VT), ultrasonic testing (UT), and inclusion content evaluation per EN 4700-001 technical specifications. Delta ferrite content must be limited to a maximum of 5%, guaranteeing microstructural quality appropriate for aerospace use.

• Dimensional and Marking Requirements
  The standard covers dimensional inspection criteria and marking prescriptions to ensure traceability and consistency in aerospace-grade steel plates.

Applications

EN 4883:2022 steel plates are ideal for use in aerospace manufacturing where strength-to-weight ratio, corrosion resistance, and durability under stress are critical. Typical applications include:

• Structural aircraft components
• Engine parts requiring high fatigue resistance
• Landing gear components
• Aerospace fasteners and fittings
• Precision machined parts in aeronautical assemblies

The standardized steel plates facilitate quality assurance between manufacturers and purchasers, ensuring reliable material performance in demanding aerospace environments.

Related Standards

• EN 4700-001: Aerospace series - Steel and heat resisting alloys - Wrought products - Technical specification for plates, sheets, and strips
• EN 4258: General organization of aerospace metallic material standards and their interrelationships
• EN 4500-005: Rules for drafting and presentation of aerospace material standards, specific to steels
• AMS 2315: Standard method for determining delta ferrite content in stainless steels and alloys

These related standards complement EN 4883:2022 by specifying material testing, presentation, and quality requirements essential for aerospace steel products.

---

By adherence to EN 4883:2022, aerospace manufacturers gain assurance of high-quality, consistently processed steel plates meeting stringent mechanical property thresholds and suitability for critical flight applications. This supports enhanced safety, performance, and compliance with international aerospace material standards.
