1 TECHNICAL SPECIFICATION TS96 ISSUE 5 Issued UNKNOWN Revised Recommendations for Similar Metallic Material Specifications and Standards NOTE: The issue status of this document remains unchanged as there have been no changes to the technical content. SAE INDUSTRY TECHNOLOGIES CONSORTIA AEROSPACE STANDARDS AND PART QUALIFICATION PROGRAM SAE Industry Technologies Consortia provides that This standard is published by SAE ITC to advance the state of technical and engineering sciences. The use of this standard is entirely voluntary and its applicability and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user. Copyright 2015 SAE ITC. FOREWORD On the 1 st January 2015 the SAE Industry Technologies Consortia (SAE ITC) acquired the ADS Aerospace Standards, previously known as the Society of British Aerospace Companies (SBAC) Aerospace Standards. The SAE ITC established in 2003 operates as a trade association as part of the SAE International Enterprise providing a unique framework serving the automotive, aerospace, and commercial vehicle sectors. Clients include private companies, government agencies, individuals, and trade associations. Building consensus and breakthrough barriers to achieve solutions, and the ways by which those solutions take shape, are tailored to each client s individual needs. The legal obligations and copyright authority of all Aerospace Standards that were issued by the ADS Group Limited are therefore assigned / transferred to the SAE ITC. These Standards are produced by the SAE ITC with the assistance of, and for the benefit of the Aerospace Industry, as part of a continuous programme of Standardisation for Aerospace application under the control of the Technical Standards Committee (TSC) of the SAE ITC. SAE ITC Standards are published as part of the series of SAE ITC Aerospace Industry Standards, and where appropriate, additional manufacturing and inspection requirements are issued as Reference Sheets (RS) or Technical Specifications (TS). It is the responsibility of those using or specifying a Standard to ensure the product, process, or manufacturer so used or specified, is appropriate for the task or role in question. The SAE ITC wishes to draw special attention to the fact Technical Specifications (TS) include testing and procedures by which a user or Design Authority can establish whether a particular manufacturer, prima facie, has the capability to produce hardware in accordance with the appropriate standards and related specifications. The SAE ITC, its servants, or representatives accept no responsibility for the continued quality of hardware items produced against the relevant drawings and specifications; this responsibility remains with the user. Whilst the SAE ITC takes all reasonable care in the preparation of its Standards, neither the SAE ITC, its officers, employees, servants, agents, or representatives, shall have any responsibility or liability whatsoever with respect to any act or omission (whether negligent or not) of whatsoever nature, or in connection with the preparation of the Standards or any part thereof. These responsibilities are those of the user or Design Authority. Users of SAE ITC Standards agree that any such liability on the part of the SAE ITC is excluded to the maximum extent permitted by law. SAE ITC Standards may be changed from time to time, and both users and manufacturers of these parts should ensure they are in possession of the latest issue of the Standards and supporting documentation before adoption or the commencement of production. It is recommended that Technical Specification TS260, Metallic Materials List of Alternative Material Standards, be consulted prior to manufacture of SAE ITC products. Each Standard is a facsimile or electronic reproduction of a master drawing and, therefore, any outline view scales stated are not necessarily reproduced accurately. A Master Index of all SAE ITC Aerospace Standards is published separately on the SAE ITC website. All references to Standards include reference to RS and TS publications. Details of this and any further information can be obtained from the SAE ITC. All rights reserved. No part of this publication may be reproduced, stored in a retrieval system or transmitted, in any form or by any means, electronic, mechanical, photocopying, recording or otherwise, without prior written permission of SAE ITC.

4 Page 2 of SCOPE This document provides a list of potential alternative metallic material specifications & standards for British Standard (BS) Aerospace & General Engineering & MoD Directorate of Technical Development (DTD). It is not, however, a design document & carries no design authority. 2. REFERENCED DOCUMENTS 2.1 Informative References The following documents, in whole or in part, are informatively referenced in this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. TS95 TS260 EN ESDU ADS Recommendations for Metallic Material Specifications & Standards to be used for New Designs. Metallic Materials List of Alternative Material Specifications & Standards Only Authorised for Use on ADS Standard Parts. Metallic materials Part 1: Conventional designation Metallic Materials Data Handbook. 2.2 Listed Publication bodies EN ESDU TS European Committee for Standardization (CEN). Available from National Standards Bodies e.g. British Standards Institution (BSI). IHS Global Inc. ADS Group Limited. 3. INTRODUCTION 3.1 In view of the difficulty in obtaining material supplies for both new & established designs, the ADS Metallic Materials Special Interest Group (MMSIG) was requested to formulate tables of similar materials to provide Potential Alternatives. 3.2 The MMSIG is aware that many of the larger Companies already possess lists of alternatives appropriate to their own products, but it is hoped that the Tables will be of help to those smaller manufacturing organisations who do not possess approved Design Teams. 3.3 The attached tables are the result of the MMSIG effort, but it is emphasised that considerable care must be taken before any specific substitution is made. In every case, it will be necessary to obtain local design & quality control approval; additionally the concurrence of the prime Contractor may be required. 3.4 Before any decision is taken to use an alternative material for a specific part, consideration must be given to all relevant mechanical & metallurgical properties, including: Strength, Ruling Section & Hardenability, Weldability, Formability, Processing Response.

5 Page 3 of The ASDSTAN designations quoted are those allocated in accordance with EN Design properties for some of the materials included in this document are available in ESDU A list of preferred specifications for new designs is contained in TS A list of alternative materials for ADS standard parts with design authority for these parts is contained in TS Reference to any EN material standard means the National implementation of that standard e.g. BS EN Reference to any pren material standard means an ASDSTAN Prestandard.
