Overview
EN 2157-2:1993 (CEN) - Aerospace series - Steel - Forging stock and forgings - Technical specification - Part 2: Forging stock specifies the particular requirements for forging stock intended for the manufacture of steel forgings. This Part 2 standard is intended to be used in conjunction with EN 2157-1 and clarifies obligations between forging stock manufacturers and purchasers. Bars and sections that conform to EN 2069-3 may be accepted as forging stock when a formal agreement ensures the requirements of EN 2157-2 are met.
This document is relevant to aerospace manufacturers, forging stock suppliers, procurement teams, and quality assurance professionals who need to manage material selection, inspection, and contractual requirements for steel forgings.
Key Topics
- Scope and intended use: Defines the application of forging stock for steel forgings in aerospace contexts.
- Interface with EN 2157-1: Part 2 is complementary to Part 1 and should be referenced together when specifying material and delivery conditions.
- Acceptance of EN 2069-3 material: Describes that bars and sections complying with EN 2069-3 can be used as forging stock provided a purchaser–manufacturer agreement is in place.
- Quality and conformity principles: Emphasizes the need for documented agreements, material verification and adherence to specified requirements before manufacture.
Applications
EN 2157-2:1993 is practical in several use cases:
- Procurement and supply chain: Use as a contractual reference when sourcing steel forging stock for aerospace components to ensure clarity on responsibilities and acceptance criteria.
- Manufacturing preparation: Guides forging shops in verifying incoming material suitability before forging operations commence.
- Quality assurance and inspection: Provides a framework to confirm that forging stock meets agreed material and dimensional expectations, reducing rework and nonconformances.
- Supplier agreements: Supports drafting supplier-purchaser agreements that explicitly align delivered stock with the standard’s requirements.
Benefits include improved traceability, consistent material acceptance practices, and clearer communication between suppliers and customers in aerospace forging projects.
