Overview

EN 4264:2020 is a European standard developed by CEN that specifies requirements for the heat resisting alloy X4NiCrMoTi43-13 used in aerospace applications. This standard covers the material in its as forged condition and applies to forging stock with dimensions a or D ≤ 200 mm. The alloy is designed for high-temperature resistance, making it suitable for critical aerospace components subjected to demanding thermal environments. The standard ensures that manufacturers and suppliers provide material meeting stringent quality and chemical composition criteria, supporting safety, reliability, and performance in aerospace engineering.

The standard is part of the Aerospace series coordinated by ASD-STAN, aligning with other metallic material standards to support consistency and traceability in aerospace materials.

Key Topics

• Material Specification:
  EN 4264:2020 defines the composition of the X4NiCrMoTi43-13 alloy, requiring a precise balance of elements including nickel, chromium, molybdenum, and titanium to ensure heat resistance. Key chemical composition ranges include:
  • Carbon (C): 0.020–0.060%
  • Chromium (Cr): 11.0–14.0%
  • Molybdenum (Mo): 5.00–6.50%
  • Titanium (Ti): 2.80–3.10%
  • Nickel + Cobalt combined: 40.0–45.0%
• Form and Dimensions:
  The standard applies exclusively to forging stock in the as forged condition, where the thickness or diameter (a or D) does not exceed 200 mm, ensuring suitability for specific aerospace component sizes.
• Manufacturing Method:
  The alloy must be produced by consumable electrode remelting to achieve required purity and structural properties.
• Mechanical Properties:
  Minimum mechanical performance characteristics include:
  • Proof stress (Rp0.2): ≥ 820 MPa
  • Tensile strength (Rm): ≥ 1140 MPa
  • Elongation: ≥ 10%
  • Reduction of area: ≥ 15%
  • Hardness: ≥ 341 HB
• Delivery Condition:
  The alloy is delivered in the as forged state (no additional heat treatment is applied before delivery).
• Inspection and Testing:
  Visual and ultrasonic inspections are mandatory to detect external and internal imperfections, with limits specified for discontinuities.
  Test samples must be prepared according to EN 2957 methods.
• Reference Heat Treatment:
  While delivered as forged, a reference heat treatment cycle is provided to guide post-delivery heat treatment if needed for specific applications.

Applications

EN 4264:2020 applies to the aerospace industry where materials must withstand high temperatures while maintaining mechanical integrity. Its primary use includes:

• Aerospace components requiring heat resistance such as turbine blades, exhaust systems, and high stress structural parts.
• Forging stock supply for manufacturing processes involving high-performance aircraft and engine parts where dimensional precision and material properties are critical.
• Selection of the X4NiCrMoTi43-13 alloy benefits engineers seeking materials with proven resistance to oxidation and thermal degradation in extreme operational environments.

Related Standards

EN 4264:2020 interacts with several other key aerospace and metallurgical standards to ensure comprehensive material quality and traceability:

• EN 2043: General requirements for semi-finished aerospace product qualification (excluding forgings and castings).
• EN 2860-2: Technical specification covering heat resisting alloys for forging stock and forgings in aerospace.
• EN 2957: Method of preparation for forged sample testing ensuring consistency in mechanical property evaluation.
• EN 4258: General organization of aerospace metallic materials standards detailing links and classification across EN standards.
• EN 4500-003: Rules for drafting heat resisting alloy material standards to maintain clarity and uniformity.
