Welding consumables - Wire electrodes, strip electrodes, wires and rods for arc welding of stainless and heat resisting steels - Classification (ISO 14343:2017)
This document 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

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, is based mainly on EN 12072 , while
that of system B, by alloy type, is mainly based upon standards used around the Pacific Rim.
