Overview

EN 2306:2017 is a CEN (ASD‑STAN) aerospace material standard that defines the requirements for heat‑resisting, nickel‑base alloy bars designated Ni‑Cr20Co3Fe3, supplied in the annealed condition for aerospace applications. It specifies composition control, permitted production and melting routes, delivery condition, heat treatment guidance and links to dimensional and inspection requirements used when supplying bars for machining or forging into high‑temperature aerospace parts.

Key topics and technical requirements

• Material designation: Nickel‑base alloy Ni‑Cr20Co3Fe3 (nominally ~20% Cr, ~3% Co, ~3% Fe with nickel balance).
• Chemical composition: The standard sets composition limits and control for alloying elements and impurities (carbon, silicon, manganese, sulfur, copper, lead, titanium, etc.). Exact ranges and analysis methods are defined in the document and agreed between manufacturer and purchaser where needed.
• Melting and refining methods: Permitted melting routes include air‑melting, vacuum melting or air melting with vacuum refining, and consumable electrode remelting; the method is to be agreed between supplier and purchaser.
• Form and production: Covers bars intended for machining and for forging; dimensional ranges refer to EN 2344 (e.g., typical round bar diameters).
• Delivery condition and heat treatment: Bars are supplied annealed (machined or descaled). The standard provides heat‑treatment conditions (reference anneal around 1 000 °C with air cooling) and guidance on soaking time relative to section thickness.
• Technical specification & inspection: Technical delivery requirements follow EN 4700‑002 and EN 2344. Test, inspection, marking, dimensional checks and product‑qualification provisions are included; specific qualification programs are agreed between manufacturer and purchaser.

Applications and who uses it

• Primary uses: Specification for bar stock used as feedstock for machining or forging into heat‑resistant aerospace components (e.g., hot‑section parts, structural elements exposed to elevated temperatures).
• Users who rely on EN 2306:2017:
  • Aerospace materials engineers and designers selecting high‑temperature alloys
  • Procurement and supply chain professionals specifying raw material for aerospace manufacture
  • Manufacturers of bars, forgings and machined components
  • Quality, inspection and certification teams ensuring compliance with CEN aerospace material standards
