Scope and field of application

This part of IS0 663 gives the technical delivery requirements for

— semi-finished products, for example blooms, billets, slabs (see note 3);

— bars (see note 3);

— wire rod;

— hot-rolled plates (see note 2);

— hammer or drop forgings (see note 3).

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, line 2 to 5 and in one of the surface conditions given in table 2.

The steels are in general intended for the fabrication of quenched and tempered and subsequently nitrided machine parts.

The requirements for mechanical properties given in this part of IS0 663 are restricted to the sizes given in table 6.


1 Related International Standards are given in annex C.

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

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