Overview

EN 4670:2010 (CEN) defines the technical requirements for the aerospace-grade stainless steel FE‑PM1507 (X1CrNiMoAlTi12‑11‑2) supplied as vacuum induction melted (VIM) and consumable electrode remelted (CER) forging stock in a softened condition. The standard applies to forgings with nominal section dimensions (a or D) up to 300 mm (note: some test and dimension clauses reference tighter limits). EN 4670:2010 is part of the EN aerospace metallic materials series and links to material qualification and presentation rules.

Key topics and requirements

• Material designation and chemistry: FE‑PM1507 (X1CrNiMoAlTi12‑11‑2). Typical elemental ranges include Cr ≈ 11.0–12.5%, Ni ≈ 10.25–11.25%, Mo ≈ 1.75–2.25%, Al ≈ 1.35–1.75%, Ti ≈ 0.20–0.50%; C, Si, Mn and N are tightly controlled (low ppm levels).
• Melting and refining: Vacuum induction melting plus consumable electrode remelting to ensure ingot cleanliness and homogeneity.
• Product form: Forging stock for subsequent forging operations (a or D ≤ 300 mm; some inspection/test limits defined for ≤ 200 mm or 75–200 mm).
• Delivery and heat-treatment states: Softened (solution treated) and optionally solution + precipitation treated. Representative heat treatments listed (e.g., solution 840–860 °C / 2 h / water quench + sub‑zero and precipitation 500–520 °C / ≥8 h).
• Mechanical and hardness limits: Specified minimums such as proof stress Rp0.2 (1,520 MPa) and tensile strength Rm (1,650 MPa) in stipulated conditions, minimum elongation and reduction-of-area values, and maximum hardness limits (e.g., ≤ 363–448 HB depending on condition). Impact requirements are given (notched KV values at ambient).
• Microstructure and cleanliness: δ‑ferrite content ≤ 2%, specified grain size acceptance, inclusion/micro‑cleanliness and macrostructure classes referenced to EN 4700‑006.
• Testing, inspection and qualification: Test pieces, sampling, marking and dimensional inspection per EN 4700‑006; product qualification per EN 2043 with agreement between manufacturer and purchaser.

Applications and users

• Practical use: specification for producers, purchasers and engineers when selecting high‑strength, corrosion‑resistant stainless steel forging stock for aerospace structural components and critical forged parts.
• Primary users: material engineers, procurement specialists, forging suppliers, heat‑treatment shops, quality/inspection teams, and aerospace designers working to EN/ASD‑STAN material frameworks.

Related standards

• EN 4700‑006 (wrought products – forging stock technical specification)
• EN 2043 (qualification of semi‑finished metallic products)
• EN 4258 (organization of aerospace material standards)
• EN 4500‑3 (rules for drafting/presentation of material standards)
