Full Description

This document specifies the general technical delivery conditions for steel flat and long products (plates/ sections/wide flats and bars) used principally for general-purpose structural steels. The steels specified in this document are intended for use in welded or bolted structures.

The specific requirements for structural steels are given in the individual parts of ISO630.

This document does not include the following structural steels, some of which are covered by other International Standards:

sheet and strip: refer to ISOTC17/SC12 Continuous mill flat rolled products;

tubular products: refer to ISOTC5/SC1 Steel tubes.

NOTE 1 Lists of standards covered by ISO/TC17/SC12 and ISO/TC5/SC1 are available on the ISO website.

NOTE 2 In all parts of ISO 630, the term of "thickness" is considered as "nominal thickness", unless otherwise stated.
