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 ).

This document was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 10, Steel for pressure purposes.

This fourth edition cancels and replaces the third edition (ISO 9328-4:2011), which has been technically revised. The following changes have been made:

• the term “product thickness” has been replaced with “nominal thickness”;
• the new steel grades X6Ni7 and X9Ni7 have been added;
• the example of ordering has been revised;
• additional steel grades have been included in Clause 11.
• Table B.1, the specifications of “P” and “S” have been changed.

A list of all the parts in the ISO 9328 series can be found on the ISO website.
