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 14174 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 14174:2004), which has been technically revised.
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 complete listing of these bodies can be

INTERNATIONAL STANDARD ISO 14174:2012(E)
Welding consumables — Fluxes for submerged arc welding and
electroslag welding — Classification
1 Scope
This International Standard specifies requirements for classification of fluxes for submerged arc welding
and electroslag welding for joining and overlay welding using wire electrodes, tubular cored electrodes, and
strip electrodes.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.
ISO 3690, Welding and allied processes — Determination of hydrogen content in arc weld metal
ISO 14171, Welding consumables — Solid wire electrodes, tubular cored electrodes and electrode/flux
combinations for submerged arc welding of non alloy and fine grain steels — Classification

stainless and heat resisting steels — Classification
ISO 80000-1:2009, Quantities and units — Part 1: General
3 Classification
Fluxes for submerged arc welding and electroslag welding for joining and overlay welding are granular, fusible
products of mainly mineral origin, which are manufactured by various methods. Fluxes influence the chemical
composition and the mechanical properties of the weld metal.
The classification of the fluxes is divided into seven parts:
1) the first part gives a symbol indicating the product/process (see 4.1);
2) the second part gives a symbol indicating the method of manufacture (see 4.2);
3) the third part gives a symbol indicating the type of flux, characteristic chemical constituents
(see Table 1);
4) the fourth part gives a symbol indicating the applications, flux class (see 4.4);
5) the fifth part gives a symbol indicating the metallurgical behaviour (see 4.5);
6) the sixth part gives a symbol indicating the type of current (see 4.6);
7) the seventh part gives a symbol indicating the diffusible hydrogen content of deposited weld metal
(see Table 6) — only applicable for class 1 fluxes.
In order to promote the use of this International Standard, the classification is divided into two sections.
a) Compulsory section.
This section includes the symbols for process, method of manufacture, characteristic chemical constituents,
and applications, i.e. the symbols defined in 4.1, 4.2, 4.3, and 4.4.
b) Optional section.

SIST EN ISO 14174:2012
ISO 14174:2012(E)
This section includes the symbols for the metallurgical behaviour, type of current, and diffusible hydrogen,
i.e. the symbols defined in 4.5, 4.6, and 4.7.
4 Symbols
4.1 Symbol for the product/process
The symbol for the flux used in submerged arc welding for joining and overlay welding shall be the letter S and
for the flux used in electroslag welding for joining and overlay welding shall be the letters ES.
4.2 Symbol for method of manufacture
The symbol below indicates the method of manufacture:
— F: fused flux;
— A: agglomerated flux;
— M: mixed flux.
Fused fluxes are made by melting and granulating. Agglomerated fluxes are bound, granular mixtures of finer
raw materials. Mixed fluxes comprise all fluxes which, after fusing or agglomerating, are mixed with one or
more additional components or fluxes.
For particle size requirements in marking, see Clause 5.
4.3 Symbol for type of flux, characteristic chemical constituents
The symbols in Table 1 indicate the type of flux in accordance with the characteristic chemical constituents.
Elemental analysis shall be performed on representative samples of the flux. Any suitable analytical technique
may be used, but in cases of dispute reference shall be made to established methods. Based on the elemental
analysis of the flux, the characteristic chemical constituents of the flux can be determined.
Examples of such determinations are shown in Annex A.
4.4 Symbol for applications, flux class
4.4.1 General
A given flux may carry more than one class as specified in 4.4.2 to 4.4.5.
4.4.2 Flux class 1
These are fluxes for submerged arc welding of non alloy and fine grain steels, high-strength steels, creep-
resisting steels, and atmospheric corrosion-resisting steels.
In general, the fluxes do not contain alloying elements, other than Mn and Si, thus the weld metal analysis is
predominantly influenced by the composition of the wire/strip electrode and metallurgical reactions. The fluxes
are suitable for joint welding and/or overlay welding. In the case of joint welding, some fluxes can be applied for
both multi-run and single-run and/or two-run technique.
In the flux designation, the digit 1 indicates class 1.

4.4.3 Flux classes 2 and 2B
These are fluxes for joint welding of stainless and heat-resisting steels and/or nickel and nickel alloys and
1)
corrosion-resistant overlay welding . Fluxes of these classes can contain alloying elements compensating for
the burn-out.
In the flux designation, the digit 2 is used to indicate class 2 fluxes mainly suited for joint welding, but which can
also be used for strip cladding. 2B is used for fluxes especially designed for strip cladding.
4.4.4 Flux class 3
These are fluxes mainly for hardfacing overlay welding by transfer of alloying elements from the flux, such
as C, Cr or Mo.
In the flux designation, the digit 3 indicates class 3.
4.4.5 Flux class 4
These are other fluxes for which classes 1 to 3 are not applicable, e.g. fluxes for copper alloys.
In the flux designation, the digit 4 indicates class 4.
4.5 Symbol for metallurgical behaviour
4.5.1 General
The metallurgical behaviour of a flux is characterized by the contribution (pick-up and/or burn-out) of alloying
elements. Concerning fluxes for joining, the contribution is the difference between the chemical composition
of the all-weld metal deposit and the composition of the specified electrode. Concerning fluxes for overlay
welding, the contribution is the difference between the chemical composition of the deposited weld metal of the
last bead/layer and the chemical composition of the specified wire/strip electrode.
4.5.1.1 Metallurgical behaviour, flux class 1
For determining the pick-up and burn-out behaviour, a wire electrode ISO 14171-A - S2 or ISO 14171-B - SU22
shall be used in accordance with 4.5.2. The pick-up or burn-out of the elements Si and Mn shall be stated in
this sequence.
The symbols in Table 2 indicate the metallurgical behaviour of a welding flux class 1.
1) Not all fluxes suitable for use with stainless steel filler metal are also suitable for nickel and nickel alloy filler metal.
