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.

Introduction

For nickel welding consumables, there is no unique relationship between the product form (solid wire

electrode, solid strip electrode, solid wire, solid rod) and the welding process used (e.g. gas shielded

metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, strip overlay

welding, laser welding or other welding processes). For this reason, the solid wire electrode, solid strip

electrode, solid wire, solid rod may 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 (see also Annex B).

nickel and nickel alloys — Classification
1 Scope

This document specifies requirements for classification of solid wire electrodes, solid strip electrodes,

solid wires, solid rods for fusion welding of nickel and nickel alloys. The classification of the solid wire

electrodes, solid strip electrodes, solid wires, and solid rods is based on their chemical composition.

The principles of this standard can be applied to metal powders for cladding, hard facing and additive

manufacturing.

4 Classification
The classification is divided into two parts:

a) the first part indicates the product form, being solid wire electrode, solid strip electrode, solid

wire, solid rod, see 5.1;

b) the second part gives a numerical symbol indicating the chemical composition of the solid wire

electrode, solid strip electrode, solid wire, solid rod, see Table 1.
5 Symbols and requirements
5.1 Symbols for the product form
The symbol for the solid wire electrode, solid wire or solid rod shall be “S”.

---------------------- Page: 9 ----------------------
oSIST prEN ISO 18274:2021
ISO/DIS 18274:2021(E)
The symbol for the solid strip electrode shall be “B”.
NOTE One product form can be used for more than one welding process.
5.2 Symbol for the chemical composition

The initial symbol “Ni” in Table 1 identifies the welding consumable as a nickel base alloy. The following

four digits indicate the chemical composition of the solid wire electrode, solid strip electrode, solid

wire or solid rod, determined under conditions given in Clause 7. The first digit is an indicator of the

alloy group as follows:

— 1, significant molybdenum addition without significant chromium addition (nickel-molybdenum

alloys);
— 2, no significant alloy addition;
— 4, significant copper addition (nickel-copper alloys);

— 5, significant copper additions with aluminium and titanium for precipitation hardening;

— 6, significant chromium addition, with iron less than 25 % (by mass) (nickel-chromium-iron and

nickel-chromium-molybdenum alloys);
— 7, same as 6, but with aluminium and titanium for precipitation hardening;

— 8, significant chromium addition, with iron more than 25 % (by mass) (nickel-iron-chromium

alloys).

The remaining digits indicate the alloy composition of the welding consumable. A description of common

uses of each welding consumable alloy is given in Annex A. The basis of the system of designation is

described in Annex B.
NOTE 1 In addition, the chemical symbol can be used.
NOTE 2 Corresponding national classifications are shown in Annex C

Any other agreed composition

Ni Z Any other agreed composition with a minimum nickel content greater than the minimum value for any other element

Single values for all elements are maxima except where the ≥ sign is used.

Symbols with R have more restricted chemical compositions compared to the symbols without R. Symbols with R meet the requirements of symbols without R

but not vice versa.

Up to 1 % (by mass) of the nickel content can be cobalt unless otherwise specified. For certain applications, lower cobalt levels may be required and should be

agreed between contracting parties.
Up to 20 % (by mass) of the niobium content can be tantalum.
The total of unspecified elements shall not exceed 0,5 % (by mass).

Phosphorus 0,020 % (by mass) maximum and sulfur 0,015 % (by mass) maximum unless otherwise stated.

Ag ≤ 0,000 5 % (by mass), B ≤ 0,020 % (by mass), Bi ≤ 0,000 1 % (by mass), Pb ≤ 0,002 0 % (by mass), Zr ≤ 0,15 % (by mass).

Consumables for which the chemical composition is not listed shall be symbolized similarly and prefixed by the letters Ni Z. The chemical composition ranges

are not specified and it is possible that two electrodes with the same Z-classification are not interchangeable.

6 Mechanical properties of the weld metal
Mechanical properties of the weld metal are not part of the classification.

NOTE Information on typical weld metal tensile strengths, where they exist, can be found in Annex C.

7 Chemical analysis

Chemical analysis shall be performed on specimens of the product or the stock from which it is made.

Any analytical technique can be used, but in case of dispute, reference shall be made to established

published methods, agreed between the contracting parties.

NOTE 1 The shielding gas or flux can influence the chemical composition of the all-weld metal as compared to

the chemical analysis of the product or stock.
NOTE 2 See Annex B.
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.

9 Retests

If any test fails to meet the requirement(s), that test shall be repeated twice. The results of both retests

shall meet the requirement. Specimens for the retest may be taken from the sample or from one or two

new samples. For chemical analysis, retests need only be for those specific elements that failed to meet

the requirement. If the results of one or both retests fail to meet the requirement, the material under

test shall be considered as not meeting the requirements of this document for that classification.

In the event that during preparation, or after completion of any test, it is clearly determined that

prescribed or proper procedures were not followed in preparing the sample(s) or test specimen(s), or

in conducting the tests, the test shall be considered invalid. This determination is made without regard

to whether the test was actually completed, or whether the test results met, or failed to meet, the

requirements. That test shall be repeated, following proper prescribed procedures. In this case, the

requirement for doubling the number of test specimens does not apply.
10 Technical delivery conditions

Technical delivery conditions shall meet the requirements of ISO 544 and ISO 14344.

11 Designation

The designation of solid wire electrodes, solid strip electrodes, solid wires and solid rods shall follow

the principle given in the examples below.

EXAMPLE 1 A solid wire (S) for gas shielded metal arc welding having a chemical composition within the

limits for the alloy symbol 6625 (NiCr22Mo9Nb) of Table 1 is designated:
