EN 2858-2:1994

Overview

EN 2858-2:1994 is a CEN aerospace series technical specification that defines the particular requirements for forging stock of grades 1 and 2 titanium and titanium alloys. The standard applies to material intended for the manufacture of titanium and titanium-alloy forgings. Unless otherwise specified, the requirements for grade 2 shall apply.

This document is intended for procurement, quality assurance and engineering teams who need a clear specification for incoming titanium forging stock used in aerospace applications.

Key Topics

The standard focuses on the particular requirements that ensure forging stock is suitable for producing reliable aerospace forgings. Key topics addressed include:

• Material scope: definition of applicability to titanium and titanium alloy forging stock, specifically grades 1 and 2.
• Grade precedence: statement that, unless otherwise specified, grade 2 requirements apply by default.
• Supply conditions: expectations for the form and delivery of forging stock for manufacturing use.
• Documentation and traceability: requirements for certificates, identification and traceability throughout the supply chain.
• Inspection and acceptance: criteria and responsibilities for verifying conformance on receipt.

Note: The summary avoids prescriptive technical values; refer to the full EN 2858-2:1994 text for detailed clauses and mandatory requirements.

Applications

EN 2858-2:1994 is applicable where controlled, documented titanium forging stock is required for critical manufacturing and aerospace components. Typical practical uses include:

• Procurement specifications for raw forging stock intended for aerospace forgings.
• Quality assurance checklists for incoming material verification.
• Technical contracts between material suppliers and manufacturers that require standardized material acceptance criteria.

Benefits of adhering to the standard:

• Improved material consistency for downstream forging operations.
• Clear traceability and documentation, supporting certification and regulatory needs.
• Reduced supply-chain ambiguity, by setting default grade rules (grade 2 precedence) and defining what constitutes acceptable forging stock.

Related Standards

For comprehensive material and manufacturing control, EN 2858-2:1994 should be used alongside other aerospace material specifications and the complementary parts of the EN 2858 series (for example, the part addressing forgings) and relevant CEN documents covering titanium metallurgy, testing and fabrication practices.

For implementation, consult the full EN 2858-2:1994 text and coordinate with suppliers to ensure certificates, marking and delivery conditions meet the specified requirements.
