Welding consumables - Wire electrodes, strip electrodes, wires and rods for arc welding of stainless and heat resisting steels - Classification (ISO/DIS 14343:2024)
ISO 14343:2017 specifies requirements for classification of wire electrodes, strip electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding of stainless and heat-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition.
This document is a combined specification providing for classification utilizing a system based upon nominal composition (system A), or utilizing a system based upon alloy type (system B).
a) Paragraphs which carry the label "classification according to nominal composition" and the suffix letter "A", or "ISO 14343-A", are applicable only to products classified according to system A;
b) Paragraphs which carry the label "classification according to alloy type" and the suffix letter "B", or "ISO 14343-B", are applicable only to products classified according to system B.
c) Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 121, Welding and allied processes, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 14343:2017), which has been technically
revised.
The main changes are as follows:
— addition of 19 L Mo Nb Si Ti, 27 7 5 N L and 29 8 2 N L in Table 1 and in Table A.1;
— addition of the designation 18 L Ti for the alloy type 439;
— change of the footnote a on the symbol classifications in parentheses;
— replacement of "G" by "SS" for the product or process symbol in example 5.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document provides a classification system for wire electrodes, strip electrodes, wires and rods for arc
welding of stainless and heat resisting steels. It recognizes that there are two somewhat different approaches
in the global market to classifying a given welding consumable, and allows for either or both to be used, to
suit a particular market need. Many, but not all, commercial products addressed by this document can be
classified using both approaches, and suitable products can also be marked.
System A uses the nominal composition approach with designators to indicate the principal alloying elements
at their nominal levels, in a particular sequence, and which is sometimes followed by chemical element
symbols to indicate compositional modifications to the original grade. System B uses the alloy type approach
with three- or four-digit designations for certain grades, sometimes followed by one or more chemical
element symbols indicating compositional modifications of the grade. In both approaches, classification is
based upon the chemical composition of the product. In many cases, a given product can be classified using
both approaches, because the composition ranges, although slightly different, overlap to a considerable
extent between the two.
For stainless steel welding consumables, there is no unique relationship between the product form (wire
electrode, strip electrode, wire or rod) and the welding process used (gas-shielded metal arc welding, gas
tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam
welding). For this reason, the wire electrodes, strip electrodes, wires or rods can be classified on the basis
of any of the above product forms and can be used, as appropriate, for more than one of the above processes.
[1]
Classification according to system A, by nominal composition, was based mainly on EN 12072, while that
of system B, by alloy type, is mainly based upon standards used around the Pacific Rim.
