Overview
EN 4528:2009 is a European aerospace material standard that specifies requirements for Steel FE-PA3903 (X10CrNi18-8) supplied as cold‑rolled strip for springs. The standard applies to strips with nominal thickness a ≤ 3 mm intended for aerospace use and defines mechanical, chemical and inspection criteria for high‑strength spring strip material with tensile strength in the range 1 250 MPa ≤ Rm ≤ 1 640 MPa.
Key topics and technical requirements
- Material designation: FE-PA3903 (X10CrNi18-8) - a chromium‑nickel stainless steel for spring applications.
- Form & production: Cold‑rolled strip, thickness a ≤ 3 mm. Method of melting: air melted. Delivery condition: temper rolled (code U).
- Mechanical properties:
- Tensile strength Rm: 1 250–1 640 MPa
- Proof stress Rp0.2: ≥ 950 MPa
- Elongation A: ≥ 4%
- Hardness: 380–480 HV
- Direction of test piece: longitudinal (L); test temperature: ambient.
- Chemical composition: Specified minimums and maximums for C, Si, Mn, P, S, Cr, Mo, Ni, Cu, N (as listed in the standard).
- Cleanliness / inclusions: Micro‑cleanness requirements per EN 2951; category 2.
- Inspection & delivery: Dimensional and marking inspections as referenced to EN 4700‑1. Product qualification and specific inspection programs are to be agreed between manufacturer and purchaser.
Applications and practical value
EN 4528:2009 is intended for specification and procurement of high‑strength spring strip for aerospace components. Typical practical uses include:
- Design and manufacture of springs and elastic elements in aerospace assemblies where high tensile strength, corrosion resistance and repeatable mechanical performance are required.
- Supplier quality specification, incoming material inspection and certification for aerospace manufacturers and tier‑1 suppliers.
- Material selection by design engineers, procurement teams and testing laboratories to ensure conformity with aerospace industry mechanical and micro‑cleanliness expectations.
Using EN 4528:2009 helps ensure traceable, repeatable material performance, reduces risk in safety‑critical spring applications, and provides a common technical language between buyers and suppliers.
