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.
NOTE 1 European Standards on similar grades are listed in Annex C.
NOTE 2 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 "forgings".
NOTE 3 Special agreements should be made when ordering un-worked continuously cast semi-finished products.
NOTE 4 In accordance with EN 10020, the steels covered by EN 10083-2:2006 are quality and special steels, the steels covered by EN 10083-3:2006 are special steels. The differences between quality and special steels are characterized by the following requirements, which are valid for special steels only:
the minimum impact values in the quenched and tempered condition (for non alloy special steels in the case of
