Overview

EN 3358:2020 is a CEN aerospace-materials standard that specifies requirements for steel FE-PM1503 (X3CrNiMoAl 13-8-2) supplied as bars for machining. The standard covers material chemistry, melting route, heat treatment, mechanical properties and acceptance criteria for bars with nominal dimension a or D ≤ 150 mm and a minimum tensile strength Rm ≥ 1 400 MPa. It is intended for aerospace applications where high-strength, heat-treatable stainless/precipitation‑hardening steel bars are required.

Key topics and technical requirements

• Material designation: FE-PM1503 (X3CrNiMoAl 13-8-2).
• Melting method: Vacuum induction melted and consumable electrode remelted (VIM + ESR).
• Form & size: Bars for machining; a or D ≤ 150 mm.
• Heat treatments (delivery conditions):
  • Solution treated: 900–950 °C, t ≥ 30 min, air cool (AC), oil quench (OQ) or water quench (WQ) to ≤ 15 °C.
  • Solution treated and precipitation treated: solution as above plus ageing at 530–550 °C for 4 h, AC.
  • Delivery condition codes: W (solution treated) and U (solution + precipitation treated).
• Mechanical properties (representative limits specified):
  • Tensile strength Rm ≥ 1 400 MPa.
  • Proof stress Rp0,2 ≥ 1 310 MPa.
  • Elongation A ≥ 9 %.
  • Reduction of area Z ≥ 45–50 % (as specified by condition/size).
• Microstructure and metallurgy:
  • δ‑ferrite content shall not exceed 2 %.
  • Grain size and microstructure requirements are referenced to EN 4700‑002.
• Inspection and testing: Dimensional, marking, ultrasonic inspection and macro/microstructural assessments referenced to EN 4700‑002, EN 4050‑1, EN 2043 and recognized practices (AMS 2315 G, ASTM A604‑07).

Applications and who uses this standard

EN 3358:2020 is intended for:

• Material engineers and metallurgists specifying high‑strength aerospace steels.
• Purchasing and quality departments procuring bars for machined aerospace components.
• Manufacturers producing VIM+ESR bars and performing solution/ageing treatments.
• Design and stress engineers validating material selection for critical machined parts.

Typical uses include high‑strength machined parts and structural components in aerospace systems where controlled chemistry, strict melting practice and high tensile strength are required.
