3、ed MaterialsUnder the Direction of theAWS Technical Activities CommitteeApproved by theAWS Board of DirectorsAbstractThis specification prescribes the requirements for classification of bare solid stainless steel electrodes (both as wire and strip) for gas metal arc welding, submerged arc welding, a
4、nd other fusion welding processes. It also includes wire and rods for use in gas tungsten arc welding and plasma arc welding. Classification is based on chemical composition of the filler metal. A guide is appended to the specification as a source of information concerning the classification system
5、employed and the intended use of the stainless steel filler metal.This specification does not include any units other than weight percent. The specifications Annex A makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be
6、 used independently of the other.AWS A5.9/A5.9M:2017 (ISO 14343:2009 MOD)iiISBN: 978-0-87171-905-8 2017 by American Welding SocietyAll rights reservedPrinted in the United States of AmericaPhotocopy Rights.

9、l standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of the American National Standards Institute (ANSI). When AWS American Nation
10、al Standards are either incorporated in, or made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standards must be
11、approved by the governmental body having statutory jurisdiction before they can become a part of those laws and regulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes the AWS standards. Where this contractual relationship exists, chan
12、ges in or deviations from requirements of an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that brings together volunteers representing varied viewpoints and interests to achieve conse
13、nsus. While AWS administers the proc-ess and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.AWS disclaims liability for any injury
14、to persons or to property, or other damages of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance on this standard. AWS also makes no guarantee or warranty as to the accuracy or completeness of

It is assumed that the use of this standard and its provisions is entrusted to appropriately qualifie
17、d and competent personnel.This standard may be superseded by new editions. This standard may also be corrected through publication of amend-ments or errata, or supplemented by publication of addenda. Information on the latest editions of AWS standards includ-ing amendments, errata, and addenda is po
18、sted on the AWS web page (www.aws.org). Users should ensure that they have the latest edition, amendments, errata, and addenda.Publication of this standard does not authorize infringement of any patent or trade name.

20、 requirements of this standard may only be obtained by sending a request, in writing, to the appropriate technical committee.

21、ith regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered. These opinions are offered solely as a convenience to users of this standard, and they do not constitute professional advice. Such opinions represent only the personal opinions of the par

In addi-tion, oral opinions are informal and should not be used as a substitute for an official interpretation.This stand
23、ard is subject to revision at any time by the AWS A5 Committee on Filler Metals and Allied Materials. It must be reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions, or deletions) and any pertinent data that may be of use in
24、improving this standard are requested and should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee on Filler Metals and Allied Materials and the author of the comments will be informed of the Committees response to the com-ments. Guests are in
25、vited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials to express their comments verbally.

30、 its chemical composition as given in Table 1.The classification is divided into two parts:(a) the first gives a symbol indicating the product/process to be identified;(b) the second gives a symbol indicating the chemical composition of the wire electrode, strip electrode, wire, or rod.See Clause 14
31、 for examples of AWS Classifications/Designations.4.2 Materials may be classified under more than one classification provided they meet all the requirements of those classifications as specified in Table 1.
