BS ISO 683-5:2017 gives the technical delivery requirements for

• semi-finished products, e.g. blooms, billets, slabs (see note 1),
• bars (see note 1),
• wire rod,
• hot-rolled plates (see note 2), and
• hammer or drop forgings (see note 1)

manufactured from the nitriding steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1, rows 2 to 5, and in one of the surface conditions given in Table 2.

The steels are generally intended for the fabrication of quenched and tempered and, subsequently, nitriding machine parts.

The requirements for mechanical properties given in this document are restricted to the sizes given in Table 6.

NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are in the following covered under semi-finished products or bars and not under the term "hammer and drop forgings".

NOTE 2 The term "plate" includes in the following also wide flats unless otherwise stated.

In special cases, variations in these technical delivery requirements or additions to these requirements can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B).

In addition to this document, the general technical delivery requirements of ISO 404 are applicable.
