EN 10084 Case hardening steels - Technical delivery conditions

1.1 This European Standard gives the technical delivery requirements for:
- semi-finished products, hot formed, for example blooms, billets, slabs (see NOTE 2 and NOTE 3),
- bars (see NOTE 2),
- rod,
- wide flats, quarto plates,
- hot-rolled sheet/plate and strip,
- hammer and drop forgings (see NOTE 2),
manufactured from the case hardening non alloyed or alloyed steels (see NOTE 4) listed in Table 3 and sup-plied 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 case-hardened (see Clause 3) machine parts.
NOTE 1 European Standards relating to steels complying with the requirements for the chemical composition in Ta-ble 3 but which are supplied in other product forms or treatment conditions than given above or are intended for special applications, and European Standards for similar steel grades are listed in the Bibliography.
NOTE 2 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are included under semi-finished products or bars and not under the term "hammer and drop forgings".
NOTE 3 Special agreements shall be made when ordering non-deformed continuously cast semi-finished products.
NOTE 4 In accordance with EN 10020, the steels covered by this European Standard are special steels.
1.2 In special cases variations in these technical delivery requirements or additions to them may form the subject of an agreement at the time of enquiry and order (see Annex A).
1.3 In addition to the specifications of this European Standard, the general technical delivery requirements of EN 10021 are applicable, unless otherwise specified.
