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.
For an explanation on 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 the following
URL: www .iso .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 10, Quality management in the field of welding.
This third edition cancels and replaces the second edition (ISO/TR 20173:2009), which has been
technically revised. The main changes compared to the previous edition are as follows:
— Table 1 and Table 2 have been completely revised;
— the layout has been editorially revised.
Requests for official interpretations of any aspect of this document should be directed to the Secretariat
of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be found at

Welding — Grouping systems for materials — American
materials
1 Scope
This document provides an American grouping system for materials for welding purposes, classified
in accordance with the grouping system of ISO/TR 15608. A number of Canadian, Australian and New
Zealand materials commonly used in North America are also included.
It can also apply for other purposes, such as heat treatment, forming, and non-destructive testing. Types
of steels are listed in accordance with the grouping system of ISO/TR 15608:2017, Table 1.
This document covers grouping systems for the following standardized materials:
— steel;
— aluminium and its alloys;
— nickel and its alloys;
— copper and its alloys;
— titanium and its alloys;
— zirconium and its alloys;
— cast irons.
