Overview

EN 2252:2024 (CEN / ASD‑STAN FE‑PL1505) defines material and inspection requirements for Steel 15CrMoV6 (W.nr. 1.7334) used for aerospace forgings with a maximum section diameter De ≤ 100 mm. This aerospace series standard specifies chemical composition, heat treatment routes, mechanical properties and non‑destructive testing levels for forgings intended to achieve tensile strength Rm between 1 080 MPa and 1 250 MPa.

Key topics and technical requirements

• Material designation: Steel 15CrMoV6 (1.7334); ASD‑STAN designation FE‑PL1505.
• Form and size: Forgings, De ≤ 100 mm; forged from forging stock per EN 4700‑005.
• Melting method: Air melted.
• Heat treatment / delivery conditions:
  • Annealed (code A) or hardened and tempered (code U).
  • Harden & temper route: quench from 955 °C – 995 °C (WQ or OQ) and temper at 595 °C – 645 °C.
  • Note: a stress‑relief tempering between quenching and tempering at ≥ 350 °C may be used to reduce quench‑crack risk.
• Mechanical properties:
  • Tensile strength Rm: 1 080 – 1 250 MPa.
  • Proof stress Rp0.2: ≥ 930 MPa (for hardened & tempered).
  • Elongation A: ≥ 10%.
  • Hardness: annealed HB ≤ 197; hardened & tempered HB 321 – 380.
  • Impact energy KV: ≥ 30 J (specified test conditions).
• Microstructure and quality:
  • Grain size G ≥ 5 (EN 4700‑006).
  • Inclusion content: Category 1 per EN 2951.
  • Ultrasonic testing (internal imperfections): Class 3.
• Testing & inspection: Test specimens, heat‑treatment control and dimensional/marking inspections per EN 4700‑006.

Applications and users

EN 2252:2024 is targeted at stakeholders who specify, manufacture, test or procure high‑strength aerospace forgings:

• Aerospace material engineers and designers selecting high‑strength steel forgings.
• Forging manufacturers and heat‑treatment shops producing 15CrMoV6 forgings.
• Quality & NDT laboratories performing inspection and acceptance testing.
• Purchasing and certification teams establishing procurement specs for structural or highly stressed aerospace components.

Practical uses include any aerospace application needing a low‑alloy, high‑strength forged steel conforming to controlled microstructure, mechanical performance and defect limits (typical use noted as “low alloy general purpose steel” in the standard).
