Overview

EN 4890:2022 is a CEN (ASD‑STAN) aerospace series standard that specifies requirements for Steel X4CrNiMo16‑5‑1 in sheet and plate form. The standard covers air‑melted, hot‑rolled, hardened and tempered material with thicknesses from 0.3 mm to 50 mm and tensile strength Rm between 900 MPa and 1 050 MPa. ASD‑STAN designation: FE‑PM 3504. EN 4890:2022 was approved by CEN on 13 March 2022 and is intended specifically for aerospace applications.

Key topics and technical requirements

• Material and melting: Steel designation X4CrNiMo16‑5‑1, produced by air melting and hot rolling (sheets and plates).
• Chemical composition (typical limits per the standard):
  • C ≤ 0.06 %, Si ≤ 0.70 %, Mn ≤ 1.50 %, P ≤ 0.040 %, S ≤ 0.015 %
  • N 0.02–0.08 %, Cr 15.00–17.00 %, Mo 0.80–1.50 %, Ni 4.00–6.00 %
• Heat treatment / delivery conditions:
  • Delivered softened or hardened and tempered.
  • Typical austenitizing: 1010 °C – 1060 °C (AC/AQ/OQ/PQ); tempering 580 °C – 650 °C, or by agreement between manufacturer and purchaser.
• Mechanical property targets:
  • Tensile strength Rm: 900–1 050 MPa.
  • Proof stress Rp0.2: ≥700 MPa for defined thickness ranges.
  • Hardness: softened condition ≤255 HB; hardened and tempered typically 280–320 HV.
  • Impact energy: specified minima (e.g., ≥120 J at 20 °C and ≥70 J at −40 °C for thicker sections where applicable).
• Metallurgical and quality limits:
  • δ‑ferrite content ≤ 5 %
  • Grain size: G ≥ 5 (per EN 4700‑001)
  • Inclusion, visual and dimensional inspections and ultrasonic testing as referenced.
• Test and inspection references: normative references include EN 4700‑001, EN 2951, and EN 4050‑4.

Applications and users

Practical applications focus on aerospace components that require high strength and reliable toughness in sheet/plate form. Typical users:

• Aircraft and aerospace manufacturers (material selection and procurement)
• Suppliers of aerospace-grade steel sheets and plates
• Design and structural engineers specifying materials for load‑bearing parts
• Quality, inspection and testing personnel ensuring compliance with aerospace material standards
• Contractors and maintenance organisations that source certified materials

Keywords for search: EN 4890:2022, X4CrNiMo16‑5‑1, aerospace steel, hardened and tempered, air melted, sheets and plates, 900–1050 MPa.
