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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

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 14172:2015), which has been technically
revised.
The main changes are as follows:
— updated to latest style including foreword;
— aligned with ISO 18274 where possible;
— updated references;
— rounding procedure is now Clause 8;
— revised the chemical compositions for a number of chemical compositions in Table 1;
— added new alloys in Table 1;
— updated corresponding entries in other parts of the document;
— new Example 2 added;
— added Chinese alloys to Table C.1

INTERNATIONAL STANDARD ISO 14172:2023(E)
Welding consumables — Covered electrodes for
manual metal arc welding of nickel and nickel alloys —
Classification
1 Scope
This document prescribes requirements for the classification of nickel and nickel-alloy covered
electrodes for manual metal arc welding and overlaying. The classification of the covered electrodes is
based on the chemical composition of their deposited all-weld metal. It includes those compositions in
which the nickel content exceeds that of any other element.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

No terms and definitions are listed in this document.

4 Classification
A covered electrode shall be classified in accordance with the chemical composition of the all-weld
metal as given in Table 1. The required mechanical properties for the classification’s all-weld metal are
listed in Table 2.
The symbol for the classification is divided into two parts:
a) the first part gives a symbol indicating the product or process to be used;
b) the second part gives a symbol indicating the chemical composition of the all-weld metal.
ISO 14172:2023(E)
5 Symbols and requirements
5.1 Symbol for the product or process
The symbol for covered electrodes used for manual metal arc welding shall be the letter “E”.
NOTE Corresponding national classifications are shown in Annex C.
5.2 Symbol for the chemical composition of the all-weld metal
The symbol for the chemical composition of the all-weld metal shall comprise “Ni” plus four digits, as
shown in Table 1. The first digit is an indicator of the class of alloy deposited, where:
1 indicates significant molybdenum addition without significant chromium addition (nickel-
molybdenum alloys);
2 indicates no significant alloy addition;
4 indicates significant copper addition (nickel-copper alloys);
6 indicates significant chromium addition, with iron less than 25 % (nickel-chromium-iron and
nickel-chromium-molybdenum alloys);
8 indicates significant chromium addition, with iron more than 25 % (nickel-iron-chromium alloys).
The remaining digits indicate the particular alloy deposited. The basis of the system of designation is
described in Annex A.
NOTE In addition, the chemical symbol can be used.
6 Chemical analysis
Chemical analysis shall be performed on any suitable all-weld metal test specimen. In case of dispute,
the test specimen specified in ISO 6847 shall be used. The test results shall meet the requirements
of Table 1 for the classification under test. Any analytical technique can be used; however, in case of
dispute, reference shall be made to established published methods.
7 Mechanical properties of the all-weld metal
Mechanical properties are not part of the designation, but they are required for classification. The
mechanical properties of the all-weld metal, deposited using covered electrodes in accordance with
Table 1, shall be determined using a test assembly type 1,3 in accordance with ISO 15792-1:2020, with
4,0 mm electrodes. The minimum tensile properties shall be in accordance with Table 2.
8 Rounding procedure
Actual test values obtained shall be subject to ISO 80000-1:2022, B.3, Rule A. If the measured values are
obtained by equipment calibrated in units other than those of this document, the measured values shall
be converted to the units of this document before rounding. If an average value is to be compared to the
requirements of this document, rounding shall be done only after calculating the average. The rounded
results shall fulfil the requirements of the appropriate table for the classification under test.

a
Symbols with B generally have more restrictive chemical compositions and are typically used in Pacific Rim countries.
b
Single values for all elements except nickel are maxima. Two values shown indicate minimum and maximum limits for a range.
c
Up to 1 % of the nickel content can be cobalt unless otherwise specified. For certain applications, lower cobalt levels can be required and should be agreed between contracting parties.
d
Up to 20 % of the niobium content can be tantalum.
e
The total of unspecified elements shall not exceed 0,5 %, excluding cobalt and tantalum.
f
Phosphorus 0,020 max., sulfur 0,015 max. unless otherwise stated.
g
Boron 0,005 % max., Zr 0,020 %.
h
Consumables for which the chemical composition is not listed in the table may be symbolized similarly and prefixed by the letter Z. The chemical composition ranges are not specified and
therefore two electrodes with the same Z-classification may not be interchangeable.
