The work
20、of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-government
21、al, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The mai
22、n task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Att
23、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24598 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 3
24、, Welding consumables. This second edition cancels and replaces the first edition (ISO 24598:2007), which has been technically revised. The main changes compared to the previous edition are: a) the composition of 9C1MV is modified on the B side of Table 3 (former Table 4) and Table 4 (former Table 5
25、); b) different test pieces in accordance with ISO 15792-1 are specified for side A and B in Clauses 5A and 5B, respectively. Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 3 via your national standards body. A

27、gnizes that there are two somewhat different approaches in the global market to classifying a given wire electrode, tubular cored electrode or electrode/flux combination, and allows for either or both to be used to suit a particular market need. Application of either type of classification designati
28、on (or of both where suitable) identifies a product as classified in accordance with this International Standard. The classification in accordance with system A is mainly based on EN 12070:19992. The classification in accordance with system B is mainly based upon standards used around the Pacific Ri
29、m. This International Standard provides a classification system for solid wire electrodes in terms of their chemical composition, solid wire electrodes and tubular cored electrodes in terms of the deposit composition obtained with a particular submerged arc flux and, where required, electrode-flux c
30、ombinations in terms of the yield strength, tensile strength and elongation of the all-weld metal deposit. The ratio of yield to tensile strength of weld metal is generally higher than that of parent metal. Users should note that matching weld metal yield strength to parent metal yield strength does
31、 not necessarily ensure that the weld metal tensile strength matches that of the parent material. Where the application requires matching tensile strength, therefore, selection of the consumable should be made by reference to column 3 of Table 1A or Table 1B, as appropriate. Although combinations of
32、 wire electrodes and fluxes supplied by individual companies can have the same classification, the individual wire electrodes and fluxes from different companies are not interchangeable unless verified in accordance with this International Standard. It should be noted that the mechanical properties
33、of all-weld metal test pieces used to classify the wire electrodes vary from those obtained in production joints because of differences in welding procedure, such as electrode size, welding position and material composition.

34、ights reserved 1Welding consumables Solid wire electrodes, tubular cored electrodes and electrode-flux combinations for submerged arc welding of creep-resisting steels Classification 1 Scope This International Standard specifies requirements for classification of solid wire electrodes, tubular cored
35、 electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature steels. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical
36、 composition. This International Standard is a combined specification providing for classification utilizing a system based upon the chemical composition of the solid wire electrode and all-weld metal deposit, or utilizing a system based upon the tensile strength of the all-weld metal deposit and th
37、e chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination. a) Clauses, subclauses and tables which carry the suffix letter “A” are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classifie
38、d in accordance with the system based upon chemical composition. b) Clauses, subclauses and tables which carry the suffix letter “B” are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon the tensile stre
39、ngth of all-weld metal deposits and the chemical composition of solid wire electrodes and all-weld metal deposits. c) Clauses, subclauses and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all solid wire electrodes, tubular cored electrodes and elect

44、o approaches to indicate the chemical composition of the solid wire electrode, the chemical composition of the all-weld metal deposit obtained with a solid wire electrode or tubular cored electrode, and the tensile properties and impact properties of the all-weld metal deposits obtained with a given
45、 electrode/flux combination. The two designation approaches include additional designators for some other classification requirements, but not all, as is clear from the provisions given in this International Standard. In many cases, a given commercial product can be classified in accordance with bot
46、h systems. Then either or both classification designations can be used for the product. A solid wire electrode shall be classified in accordance with its chemical composition as given in Table 3. An all-weld metal deposit from a solid wire electrode or tubular cored electrode shall be classified in
47、accordance with the all-weld metal deposit composition, as given in Table 4, obtained with a particular flux. When the solid wire electrode or tubular cored electrode is classified in combination with a flux for submerged arc welding, the classification shall be prefixed with a symbol in accordance
48、with Clause 4 as appropriate. 3A Classification by chemical composition 3B Classification by tensile strength and chemical composition The classification is divided into three parts: The classification is divided into five parts: 1) the first part gives a symbol indicating theproduct or process to b
49、e identified; 1) the first part gives a symbol indicating the product or process to be identified; 2) the second part gives a symbol indicating thechemical composition of the solid wire electrode(see Table 3) and all-weld metal deposit (seeTable 4); 2) the second part gives a symbol indicating the strength and elongation of the all-weld metaldeposit in the post-weld heat-treated condition (see Table 1B); 3) the third part gives a symbol indicating the impact properties of all-weld metal deposits in the same condition
