Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work 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-governmental, 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 main 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.
Attention 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, 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);
b) different test pieces in accordance with ISO 15792-1 are specified for side A and B in Clauses 5A and 5B,
respectively.

Introduction
This International Standard recognizes 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
designation (or of both where suitable) identifies a product as classified in accordance with this International
[2]
Standard. The classification in accordance with system A is mainly based on EN 12070:1999 . The
classification in accordance with system B is mainly based upon standards used around the Pacific Rim.
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 combinations 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 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 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 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.

INTERNATIONAL STANDARD ISO 24598:2012(E)
Welding 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
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 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 the 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 classified 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 strength 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 electrode/flux combinations classified
under this International Standard.

3 Classification
Classification designations are based upon two 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 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 both
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
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 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 the 1) the first part gives a symbol indicating the
product or process to be identified; product or process to be identified;
2) the second part gives a symbol indicating the 2) the second part gives a symbol indicating the
chemical composition of the solid wire electrode strength and elongation of the all-weld metal
(see Table 3) and all-weld metal deposit (see deposit in the post-weld heat-treated condition
Table 4); (see Table 1B);
3) the third part gives a symbol indicating the
impact properties of all-weld metal deposits in
the same condition as specified for the tensile
strength (see Table 2B);
3) the third part gives a symbol indicating the type 4) the fourth part gives a symbol indicating the
of flux used (see 4.5). type of flux used (see 4.5);
5) the fifth part gives a symbol indicating the
chemical composition of the solid wire
electrode, if used (see Table 3), and of the all-
weld metal deposited by an electrode/flux
combination (see Table 4).
