Welding consumables - Tubular cored electrodes and rods for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels - Classification (ISO 17633:2010)
ISO 17633:2010 specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of electrode core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels.
ISO 17633:2010 is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but ISO 17633:2010 does not use pulsed current for determining the electrode classification.

Diese Internationale Norm legt Anforderungen für die Einteilung von Fülldrahtelektroden und Füllstäben mit schlackebildender und Metallpulver-Füllung zum Metall-Lichtbogenschweißen mit oder ohne Gasschutz von korrosionsbeständigen und hitzebeständigen Stählen fest. Die Einteilung beruht auf der chemischen Zusammensetzung des reinen Schweißgutes, der Art der Füllung, dem Schutzgas, der Schweißposition und den mechanischen Eigenschaften des reinen Schweißgutes im Schweißzustand oder nach einer Wärmenachbehandlung.
Diese Internationale Norm ist eine kombinierte Norm und benutzt zur Einteilung ein System entsprechend der Nennzusammensetzung oder entsprechend auf dem Legierungstyp.
1) Abschnitte und Tabellen mit der Bezeichnung „Einteilung nach der Nennzusammensetzung“ sind nur für solche Produkte anwendbar, die nach diesem System eingeteilt sind;
2) Abschnitte und Tabellen mit der Bezeichnung „Einteilung nach dem Legierungstyp“ sind nur für solche Produkte anwendbar, die nach diesem System eingeteilt sind;
3) Abschnitte und Tabellen ohne eine dieser Bezeichnungen sind für Produkte anwendbar, die nach einem oder beiden Systemen eingeteilt sind.
Es ist bekannt, dass die Schweißeigenschaften von Fülldrahtelektroden durch die Anwendung von pulsierendem Strom beeinflusst werden können, jedoch ist in dieser Internationalen Norm pulsierender Strom nicht für die Einteilung der Fülldrahtelektroden vorgesehen.

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.
ISO 17633 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 17633:2004), of which it constitutes a technical
revision.

Introduction
This International Standard provides a classification system for tubular cored electrodes and rods for welding
stainless steels. It recognizes that there are two somewhat different approaches in the global market to
classifying a given tubular stainless steel welding consumable, and allows for either or both to be used, to suit
a particular market need. Application of either type of classification designation (or of both, where suitable)
identifies a product as classified in accordance with this International Standard.
[2]
The classification according to system A is mainly based on EN 12073:1999 . The classification according to
system B is mainly based upon standards used around the Pacific Rim.

INTERNATIONAL STANDARD ISO 17633:2010(E)
Welding consumables — Tubular cored electrodes and rods
for gas shielded and non-gas shielded metal arc welding of
stainless and heat-resisting steels — Classification
1 Scope
This International Standard specifies requirements for classification of tubular flux and metal cored electrodes
and rods, based on the all-weld metal chemical composition, the type of electrode core, shielding gas, welding
position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas
shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels.
This International Standard is a combined standard providing for classification utilizing a system based upon
nominal composition or utilizing a system based upon alloy type.
a) Clauses, subclauses, and tables which carry the suffix letter “A” are applicable only to products classified
using the system based upon nominal composition.
b) Clauses, subclauses, and tables which carry the suffix letter “B” are applicable only to products classified
using the system based upon alloy type.
c) Clauses, subclauses, and tables which do not have either the suffix letter “A” or the suffix letter “B” are
applicable to all tubular cored electrodes classified in accordance with this International Standard.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of
pulsed current. However, this International Standard does not use pulsed current for determining the electrode
classification.

3 Classification
Classification designations are based upon two approaches to indicating the chemical composition of the all-
weld metal deposit obtained with a given electrode or rod.
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 occasional additional character or characters
for compositional modifications of each original alloy within the family.
This clause includes the symbols for the type of product, the chemical composition of all-weld metal, the type
of electrode core, the shielding gas and the welding position, in accordance with the symbols defined in
Clause 4.
In most cases, a given commercial product can be classified in both systems. Then either or both
classification designations can be used for the product.
3A Classification according to nominal 3B Classification according to alloy type
composition
The classification is divided into five parts: The classification is divided into five parts:
a) the first part gives a symbol indicating the a) the first part gives a symbol indicating the
product to be identified (see 4.1A); tubular cored electrode and rod (see 4.1B);
b) the second part gives a symbol indicating the b) the second part gives a symbol indicating the
chemical composition of the all-weld metal (see chemical composition of the all-weld metal (see
Table 1A); Tables 1B-1 to -4);
c) the third part gives a symbol indicating the type c) the third part gives a symbol indicating the type
of electrode core (see Table 3A); of tubular cored electrode or rod (see Table 3B);
d) the fourth part gives a symbol indicating the d) the fourth part gives a symbol indicating the
shielding gas (see 4.4); shielding gas (see 4.4);
e) the fifth part gives a symbol indicating the e) the fifth part gives a symbol indicating the
welding position (see Table 4A). welding position (see Table 4B).
The full identification (see Clause 11) shall be used on packages and in the manufacturer's literature and data
sheets.
4 Symbols and requirements
A given tubular cored electrode may be classified with more than one shielding gas. In such cases, each
shielding gas results in a separate classification.

c
The sum of P and S shall not exceed 0,050 % (by mass), except for 18 16 5 N L, 18 8 Mn, and 29 9.
d
Up to 20 % (by mass) of the amount of Nb can be replaced by Ta.
e
The all-weld metal is in most cases fully austenitic and therefore can be susceptible to microfissuring or hot cracking. The occurrence of fissuring or cracking is reduced by increasing the weld
metal manganese level and in recognition of this the manganese range is extended for a number of grades.
f
Consumables for which the chemical composition is not listed shall be symbolized similarly and prefixed by the letter Z. The chemical composition ranges are not specified and it is possible
that two electrodes with the same Z classification are not interchangeable.
