Full title and description

STB BS EN 2302-2023 — official designation BS EN 2302:2023 / EN 2302:2023. Aerospace series — Heat‑resisting nickel base alloy NiCr20Co3Fe3; Rm ≥ 650 MPa; sheets and strips, cold rolled; thickness range 0,25 mm < a ≤ 3 mm. This document specifies the product definition, mechanical property requirement and applicable product form for aerospace applications of this nickel‑base alloy.

Abstract

This standard defines requirements for heat‑resisting nickel base alloy NiCr20Co3Fe3 in the form of cold‑rolled sheets and strips for aerospace use. It sets chemical and mechanical property limits (notably a minimum tensile strength Rm ≥ 650 MPa), applicable thickness range, and the required conformity checks and documentation to ensure material suitability for aircraft and space applications.

Scope

This document specifies the technical requirements for heat‑resisting nickel base alloy NiCr20Co3Fe3 in the product forms of sheets and strips that have been cold rolled with a nominal thickness range 0,25 mm < a ≤ 3 mm. It applies to material intended for aerospace applications and covers composition, mechanical property limits (including tensile strength Rm ≥ 650 MPa), dimensional and surface requirements, marking and accompanying documentation needed to demonstrate conformity. National adoptions (e.g. BS EN, DIN EN, UNE‑EN) retain identical technical content.

Key topics and requirements

• Designation and chemical composition for NiCr20Co3Fe3 alloy (limits for Ni, Cr, Co, Fe and other specified elements).
• Mechanical property requirement: minimum tensile strength Rm ≥ 650 MPa for the specified product condition and thickness range.
• Product form: cold‑rolled sheets and strips with thickness 0,25 mm < a ≤ 3 mm — dimensional tolerances and permissible thickness classes.
• Inspection and testing: requirements for sampling, tensile testing, and material verification to demonstrate compliance with the standard.
• Marking, certification and traceability: required information on delivery documents and material certificates for aerospace supply chains.

Typical use and users

Intended users are aerospace materials engineers, purchasing and quality teams in aircraft and spacecraft manufacturing, material suppliers and processors (sheet/strip producers), testing laboratories, and certification bodies. Typical applications include structural and high‑temperature components where a heat‑resisting nickel alloy in sheet/strip form with the specified strength is required. The standard supports procurement specifications, supplier qualifications and conformity assessment in the aerospace supply chain.

Related standards

Other standards in the aerospace series covering heat‑resisting nickel alloys and related product forms are related (examples include EN/BS EN series standards for wires, annealed or differently processed product forms such as EN 2402 / EN 2400 and other alloy‑specific documents). EN 2302:2023 is published by CEN and has identical national adoptions (BS EN 2302:2023, DIN EN 2302:2023, UNE‑EN 2302:2023, etc.). Users should check companion CEN/EN aerospace material standards for complementary test methods and product forms.

FAQ

Q: What is this standard?

A: EN 2302:2023 (published as BS EN 2302:2023 for the UK adoption) is a CEN European aerospace series standard that specifies product and property requirements for the heat‑resisting nickel base alloy NiCr20Co3Fe3 in cold‑rolled sheets and strips (thickness 0,25 mm < a ≤ 3 mm).

Q: What does it cover?

A: It covers alloy designation and composition limits, mechanical property requirements (notably a minimum tensile strength Rm ≥ 650 MPa), dimensional range and tolerances for sheets and strips, inspection and testing requirements, marking and documentation needed for aerospace supply.

Q: Who typically uses it?

A: Aerospace materials engineers, suppliers of nickel‑base sheet and strip, procurement and quality personnel in aircraft/space manufacturing, testing laboratories and conformity assessors responsible for ensuring supplied material meets aerospace performance and traceability requirements.

Q: Is it current or superseded?

A: It is current (2023 edition) — EN 2302:2023 was approved by CEN in mid‑2023 and published in 2023; the BS EN version carries the same technical content as the EN. Users should verify any later amendments or national variances before procurement.

Q: Is it part of a series?

A: Yes — it is part of the CEN “Aerospace series” of material standards covering heat‑resisting nickel alloys and other metallic materials used in aircraft and space applications. Related EN/BS EN documents address other alloys and product forms (wire, annealed conditions, alternative dimensions).
