1.1 This European Standard gives the technical delivery requirements for
— semi-finished products, hot formed, e.g. blooms, billets, slabs (see notes 2 and 3),
— bars (see note 2),
— rod,
— wide flats,
— hot or cold rolled sheet/plate and strip,
— hammer and drop forgings (see note 2),
manufactured from the direct hardening unalloyed steels (see note 4) listed in table 3 and supplied in one of the heat treatment conditions given for the different types of products in table 1, lines 2 to 7, and in one of the surface conditions given in table 2.

The steels are, in general, intended for the fabrication of quenched and tempered machine parts, but are partly (see table 7) also used in the normalized condition.

The requirements for mechanical properties given in this European Standard are restricted to the sizes given in tables 6 and 7.
