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 3581 was prepared in collaboration with the International Institute of Welding which has been approved
by the ISO Council as an international standardizing body in the field of welding.
This second edition cancels and replaces the first edition (ISO 3581:1976), which has been technically
revised.

Introduction
This International Standard provides a classification system for stainless steel, covered welding electrodes in
terms of chemical composition of deposited weld metal and type of electrode covering. Other properties of the
electrodes are specified by reference to tables.
This International Standard has been prepared by the International Institute of Welding, Commission II “Arc
Welding”, Subcommission II-E. It recognizes that there are two somewhat different approaches in the global
market, for classifying a given stainless steel, covered electrode, and allows for either or both to be used to
suit a particular need. Application of either (or both) type(s) of classification designation identifies a product as
classified according to this International Standard. It should be noted that the two systems are not exactly
equivalent, therefore each system must be used independent of the other, without combining designators in
any way.
The classification according to ISO 3581, system A, is mainly based upon EN 1600; the classification
according to ISO 3581, system B, is mainly based upon standards used around the Pacific Rim.

Classification
1 Scope
This International Standard specifies requirements for classification of covered electrodes, based on the all-
weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-
weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of
stainless and heat-resisting steels.
This International Standard is a combined standard providing for classification utilizing a system based upon
classification according to nominal composition, or utilizing a system based upon classification according to
alloy type.
a) Paragraphs and tables which carry the label “classification according to nominal composition” or
“ISO 3581-A” are applicable only to products classified to that system.
b) Paragraphs and tables which carry the label “classification according to alloy type” or “ISO 3581-B” are
applicable only to products classified to that system.
c) Paragraphs and tables which carry neither label are applicable to products classified according to either
or both systems.

3 Classification
Classification designations are based upon two approaches for indicating the chemical composition of the all-
weld metal deposit obtained with a given electrode.
The “nominal composition” approach uses designation components indicating directly the nominal levels of
certain alloying elements, given in a particular order, and some symbols for low but significant levels of other
elements, whose levels are not conveniently expressed as integers. The “alloy type” approach uses tradition-
based three- or four-digit designations for alloy families, and an occasionally additional character or characters
for compositional modifications of each original alloy within the family. Both designation approaches include
additional designators for some other classification requirements, but not entirely the same classification
requirements, as will be clear from the following sections.
Table 1 lists the tests required for classification of an electrode in each approach.
In many cases, a given commercial product can be classified using both approaches. Then either or both
classification designations can be used for the product.
