Overview

EN 3364:2022 is a CEN aerospace-series material standard that specifies requirements for Steel X5CrNiCu15‑5 (1.4545) supplied as consumable‑electrode remelted, softened forging stocks with a or D ≤ 300 mm. It is intended for aerospace applications and defines chemical composition, production method, delivery condition, heat treatment options and key mechanical and quality criteria for forgings.

Key topics and technical requirements

• Material designation: X5CrNiCu15‑5 (1.4545) - composition limits are given for C, Si, Mn, P, S, Cr, Ni, Cu, Nb+Ta and Fe (balance).
• Melting method: Consumable electrode remelted (improved cleanliness and homogeneity).
• Form & size: Forging stock, maximum characteristic dimension a or diameter D ≤ 300 mm.
• Delivery condition: Softened (delivery condition code U).
• Heat treatments: Solution treatment 1 025–1 055 °C, t ≥ 30 min, air cool (or oil quench) to ≤ 30 °C, followed by precipitation treatment:
  • Test A: 565–595 °C, t ≥ 4 h, air cool
  • Test B: 465–495 °C, t ≥ 1 h, air cool
• Mechanical properties (representative ranges): Standard defines two test conditions (Test A and Test B). Example values include proof stress (Rp0.2) in the order of 1 000–1 170 MPa, tensile strength (Rm) ≈ 1 170–1 310 MPa, elongation A% ≈ 5–11%, reduction of area Z ≈ 15–45%, and Brinell hardness ranges depending on condition (see table in EN 3364:2022).
• Microstructure and cleanliness: δ‑ferrite ≤ 2%; inclusion content Category 4; macrostructure and internal imperfection acceptance levels specified (visual testing VT, ultrasonic testing UT class 3 for internal defects).
• Testing & samples: Forged sample preparation per EN 2957; technical specification and inspection/testing per EN 2157‑2. Product qualification per EN 2043.

Applications and users

• Primary use: Specification for aerospace forging stock where corrosion resistance, high strength and predictable heat‑treatment response are required (rotating parts, structural forgings, landing‑gear components, etc.).
• Who uses it: Aerospace material engineers, procurement/specification writers, forging manufacturers, metallurgists, quality/inspection teams, and certification bodies involved in aerospace component manufacture and supply chains.
