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.

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.

product, dimensions, tolerances and markings

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/process to be used;

b) the second part gives a symbol indicating the chemical composition of the all-weld metal.

ISO/DIS 14172:2022(E)
5 Symbols and requirements
5.1 Symbol for the product/process

The symbol for covered electrodes used for manual metal arc welding shall be the letter “E”.

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; but, 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 80000-1:2009, 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.

Single values for all elements except nickel are maxima. Two values shown indicate minimum and maximum limits for a range.

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.

Up to 20 % of the niobium content can be tantalum.

The total of unspecified elements shall not exceed 0,5 %, excluding cobalt and tantalum.

Phosphorus 0,020 max., sulfur 0,015 max. unless otherwise stated.
Boron 0,005 % max., Zr 0,020 %.
