Overview

SIST EN 4315:2026 is a European standard developed by CEN for the aerospace sector, specifying comprehensive requirements for the heat-resisting alloy X6NiCrTiMoV26-15 (1.4980). This standard covers consumable electrode remelted, solution treated, and precipitation treated bars and sections with dimensions a or D ≤ 100 mm and a minimum ultimate tensile strength (Rm) of 900 MPa. SIST EN 4315:2026 replaces EN 4315:2007, featuring updated materials designations and harmonization with related specifications for improved clarity and alignment with aerospace metallic material requirements.

The specification ensures aerospace manufacturers and suppliers use materials that meet strict performance and safety criteria under demanding thermal and mechanical conditions. The standard is also referenced by ASD-STAN as FE-PA2601.

Key Topics

• Alloy Specification: Defines the heat-resisting alloy X6NiCrTiMoV26-15 (1.4980) for aerospace applications.
• Production Methods: Bars and sections must be consumable electrode remelted, ensuring superior cleanliness and structural integrity.
• Heat Treatment: Specifies both solution treated and precipitation treated conditions to optimize mechanical properties for high-stress, high-temperature environments.
• Dimensional Limits: Applies to products with a diameter or thickness (a or D) up to 100 mm, addressing the needs of high-precision aerospace components.
• Mechanical Requirements: Ensures a minimum tensile strength (Rm) of 900 MPa and proof stress (Rp0.2) of at least 590 MPa, alongside controlled hardness and elongation values for reliable performance.
• Quality Assurance: Details requirements for grain size, macrostructure, internal/external imperfections, and testing procedures, including visual and ultrasonic inspections, as well as product qualification protocols.
• Certification and Traceability: Requires rigorous marking and dimensional compliance per EN 4700-002 and related standards.
• Applicable Standards: References relevant requirements such as EN 2043 for product qualification and EN 4700-002 for technical and testing specifications.

Applications

SIST EN 4315:2026 is fundamental for the procurement and qualification of high-performance heat-resisting alloy products for aerospace use. The standard is directly applicable in:

• Aero-engine and turbine components: Where strength, thermal resistance, and dimensional stability are critical under cyclic loading and high temperature.
• Airframe structures: Components requiring high tensile strength and resistance to oxidation at elevated temperatures.
• Landing gear and structural supports: Parts subject to significant loads and potential temperature fluctuations during operation.
• Certified aerospace supply chains: Specifiers and suppliers align with SIST EN 4315:2026 to ensure compliance with regulatory and client requirements, minimizing risk and failure in mission-critical applications.
• Aerospace materials testing laboratories: For standardizing test methods and acceptance criteria for bars and sections of heat-resisting alloys.

Related Standards

For a holistic view of metallic materials standardization in aerospace, the following documents provide complementary guidance:

• EN 2043: Aerospace series - Metallic materials - General requirements for semi-finished product qualification, excluding forgings and castings.
• EN 4700-002: Aerospace series - Steel and heat resisting alloys - Wrought products - Bars and sections - Technical specification.
• EN 4258: Reference for the general organization of standardization and linkage among European standards for metallic materials.
• EN 4500-003: Rules for drafting and presenting material standards for heat-resisting alloys in the aerospace sector.

By adhering to SIST EN 4315:2026, aerospace companies ensure material consistency, meet rigorous safety and performance benchmarks, and maintain compliance with European regulations and international aerospace supply expectations. This standard is an essential reference for procurement, engineering, and quality management teams working with advanced high-temperature nickel alloys in the aerospace industry.
