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 Tiêu chuẩn iso 00683 1 2016 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 OÍ the ISO/IEC Directives, Part 2 (see www.iso.org/dircctivcs Tiêu chuẩn iso 00683 1 2016 ).

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 Tiêu chuẩn iso 00683 1 2016 not constitute an endorsement.

The committee responsible for this document is ISO/TC 17, Steel, Subcommittee sc 4, Heat treatable and alloy steels.

This third edition cancels and Tiêu chuẩn iso 00683 1 2016 replaces the second edition (ISO 683-1:2012), of which it constitutes a minor revision.

ISO 683 consists of the following parts, under the general title Heat-treatable steels, alloy steels and free- cutting steels:

• —  Part 1: Non-alloy steels for quenching and tempering

• —  Part 2: Alloy steels for quenching and tempering

• —  Part 3: Case-hardening steels

• —  Part 4: Free-cutting steels

• —  Part 5: Nitriding steels

• —  Part 14: Hot Tiêu chuẩn iso 00683 1 2016 -rolled steels for quenched and tempered springs

• —  Part 15: Valve steels for internal combustion engines

• —  Part 17: Ball and roller bearing steels

• —  Part J8: Brigh t steel products
