Welding consumables - Solid wire electrodes, tubular cored electrodes and electrode-flux combinations for submerged arc welding of high strength steels - Classification (ISO 26304:2008, including Cor 1:2009)
ISO 26304:2008 specifies requirements for classification of solid wire electrodes, tubular cored electrodes, and electrode/flux combinations (all-weld metal deposits) in the as-welded condition and in the post weld heat-treated condition for submerged arc welding of high strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa. One flux can be tested and classified with different electrodes. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition.
ISO 26304:2008 is a combined specification providing for classification utilizing a system based upon the yield strength and average impact energy of 47 J for all-weld metal, or utilizing a system based upon the tensile strength and average impact energy of 27 J for all-weld metal.

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 26304 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
Requests for official interpretations of technical aspects of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 3 via the user's national standardization body; a listing of these bodies can be

Introduction
This International Standard provides a classification in order to designate solid wire electrodes in terms of their
chemical composition, 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, elongation and impact properties of the all-weld metal. 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 will 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 electrodes and fluxes supplied by individual companies may have the same grading,
the combination of an electrode with a flux from one manufacturer versus the flux from another manufacturer,
both fluxes having the same classification, may not be interchangeable unless verified according to this
International Standard. Two tubular cored wires of the same classification may likewise produce different
results with the same flux.
It should be noted that the mechanical properties of all-weld metal test specimens used to classify the
electrode/flux combinations will vary from those obtained in production joints because of differences in welding
procedure such as electrode size, width of weave, welding position and material composition.
ISO 26304 was prepared with assistance from the International Institute of Welding, Commission II. It
