EN 2858-3:1994

Overview

EN 2858-3:1994 is a crucial European standard within the aerospace sector, focusing on titanium and titanium alloys specifically used in forging stock and forgings. Published by CEN, this standard outlines the technical specifications for pre-production and production forgings derived from forging stock that complies with the related standard EN 2858-2. It serves as a vital guideline to ensure quality, consistency, and reliability in aerospace manufacturing where titanium's strength-to-weight ratio and corrosion resistance are essential.

This standard is intended to be used in conjunction with EN 2858-1, providing comprehensive coverage of manufacturing requirements throughout the titanium forging lifecycle-starting from raw material stock to finished forgings ready for aerospace applications.

Key Topics

• Scope and Application: Defines requirements for titanium and titanium alloys forgings, including shapes and sizes used in aerospace.
• Material Compliance: Mandates that forging stock must meet the criteria established in EN 2858-2, ensuring raw material consistency before forging.
• Production Forgings Requirements: Details technical parameters for pre-production prototypes and final production forgings.
• Quality Assurance: Specifies inspection, testing, and traceability procedures to uphold manufacturing integrity.
• Manufacturing Controls: Emphasizes control of forging processes to maintain mechanical properties and dimensions suitable for aerospace use.
• Documentation: Stipulates the documentation necessary to accompany forged products for verification and certification purposes.

Applications

The EN 2858-3:1994 standard is primarily applied in the aerospace industry where titanium and its alloys play a critical role due to their high strength, lightweight, and corrosion resistance. Key practical applications include:

• Aircraft Structural Components: Forged parts like wing spars, engine mounts, and fuselage elements.
• Aerospace Engine Parts: Turbine blades, compressor discs, and shafts benefiting from titanium's durability under extreme conditions.
• Spacecraft Mechanisms: Lightweight, high-strength components for satellites and launch vehicles.
• Prototyping and Production Runs: Supporting initial prototyping to full-scale manufacturing with consistent quality standards.

By adhering to this standard, manufacturers ensure the safety, efficiency, and reliability of aerospace components, reducing risk of failure and enhancing performance.
