scope:

This part of EN 10083 specifies the general 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-rolled strip and sheet/plate, forgings (see NOTE 2) manufactured from the direct hardening non alloy steels for quenching and tempering (see EN 10083-2), the direct hardening alloy steels for quenching and tempering (see EN 10083-3), the non alloy flame and induction hardening steels (see EN 10083-2) and the alloy flame and induction hardening steels (see EN 10083-3), and supplied in one of the heat treatment conditions given for the different types of products in the relevant tables of EN 10083-2 and EN 10083-3 and in one of the surface conditions given in the relevant tables of EN 10083- 2 and EN 10083-3. The steels are generally intended for the manufacture of quenched and tempered, flame or induction hardened machine parts, but can also be used in the normalized condition (see EN 10083-2). Where applicable, the requirements for mechanical properties given in EN 10083-2 and EN 10083-3 are restricted to the relevant tables in these documents.
