Overview

SIST EN 2959:2019 is a European standard published by CEN that specifies the technical requirements for the aerospace heat resisting alloy NI-PH1302 (NiCr20Co13Mo4Ti3Al). This standard covers solution treated and cold worked bars designed specifically for forged fasteners with diameters ranging from 3 mm to 30 mm. Tailored for aerospace industry applications, the document ensures material consistency, performance, and safety in demanding environments where heat resistance and mechanical strength are critical.

Key Topics

• Material Specification: The alloy NI-PH1302 is defined by its chemical composition, including key elements such as Nickel (Ni), Chromium (Cr), Cobalt (Co), Molybdenum (Mo), Titanium (Ti), and Aluminum (Al). Precise concentration limits are defined to optimize heat resistance and mechanical properties.
• Heat Treatment: The bars undergo solution treatment between 1010 °C to 1080 °C, followed by cold working (10% to 30%) at temperatures below 870 °C. These processes enhance strength and durability.
• Physical Dimensions: The standard applies strictly to bars with diameters between 3 mm and 30 mm, ensuring suitability for forging processes related to aerospace fasteners.
• Mechanical Properties: Minimum proof stress, tensile strength, elongation, reduction of area, and hardness values are specified to guarantee performance under operational stresses and temperatures.
• Manufacturing Requirements: The bars must be vacuum melted and consumable electrode remelted to ensure purity and quality.
• Quality Control: Requirements for grain size, dimensional tolerances, external defect inspection, and marking ensure compliance with aerospace safety standards.

Applications

SIST EN 2959:2019 is critical for manufacturers and engineers involved in producing aerospace forged fasteners such as bolts, nuts, and other fastening elements used in aircraft and aerospace vehicles. The material's heat resistance and mechanical reliability make it suitable for components exposed to high temperatures and mechanical stresses, including:

• Jet engine components
• Airframe fasteners exposed to elevated temperatures
• Turbine fasteners requiring high strength and corrosion resistance
• Structural aerospace assemblies needing durable, heat-resistant fixation elements

By adhering to this standard, aerospace manufacturers can ensure fasteners meet rigorous safety and performance criteria required in the aerospace sector, improving reliability and lifecycle performance.

Related Standards

This standard is part of the comprehensive series of EN metallic material specifications tailored for aerospace applications and references related standards to ensure holistic quality management:

• EN 2043 – Aerospace series: General requirements for semi-finished product qualification (excluding forgings and castings).
• EN 4258 – General organization of aerospace material standardization and classification framework.
• EN 4500-003 – Specific rules for drafting and presentation of material standards for heat resisting alloys.
• EN 4700-002 – Technical specifications for wrought steel and heat resisting alloy bars and sections, detailing testing and inspection procedures.

Compliance with SIST EN 2959:2019 along with these associated standards ensures robust quality systems and harmonization across aerospace material supply chains.
