Overview

SIST EN 4317:2026 is a European standard developed by CEN, focusing on the requirements for heat-resisting alloy X6NiCrTiMoV26-15 (material number 1.4980) for aerospace applications. This document specifies the technical criteria for consumable electrode remelted, not heat treated, forging stock with a maximum dimension (a or D) of 200 mm. The standard outlines the necessary properties, production methods, and testing protocols to ensure consistent quality and performance of forging stock used in demanding aerospace environments.

Key identifiers for this alloy and product form include:

• Heat-resisting alloy X6NiCrTiMoV26-15 (1.4980)
• Consumable electrode remelted
• Not heat treated
• Forging stock
• a or D ≤ 200 mm
• ASD-STAN designation: FE-PA2601

Key Topics

• Material Designation: The specification applies to heat-resisting alloy X6NiCrTiMoV26-15 (1.4980), well known for its high strength and oxidation resistance at elevated temperatures, making it suitable for aerospace components.
• Production Method: The alloy is produced by consumable electrode remelting, a process that enhances material purity and uniformity, critical for aerospace safety and reliability.
• Delivery Condition: The forging stock is supplied not heat treated, allowing further processing or heat treatment as required by the end-user.
• Dimensional Limits: This standard covers forging stock where the diameter or thickness (a or D) does not exceed 200 mm.
• Quality Assurance and Testing:
  • Alignment with EN 4700-005 for forging stock
  • Requirements for chemical composition, mechanical properties, macrostructure, and non-destructive testing (visual and ultrasonic inspection)
  • Product qualification commensurate with EN 2043 for semi-finished metallic materials

Applications

• Aerospace Manufacturing: SIST EN 4317:2026 is tailored for aerospace component manufacturers requiring forging stock that meets strict quality and performance standards. Parts produced from X6NiCrTiMoV26-15 (1.4980) are commonly found in:
  • Structural components
  • Engine parts
  • High-temperature assemblies
• Supply Chain Consistency: The standard ensures manufacturers and suppliers across different countries can specify and obtain equivalent, interchangeable forging materials for aerospace projects.
• Qualification and Traceability: The precise requirements regarding product qualification and testing allow for clear traceability and quality assurance, supporting aerospace safety regulations and procurement best practices.
