BS EN 10084 is the European standard that gives the technical delivery requirements for steels that are in general intended for the fabrication of case-hardened machine parts.

It is applicable to steel in the following formats:

  • Semi-finished products, hot formed, for example blooms, billets, slabs:
  • Bars
  • Rod
  • Wide flats, quarto plates
  • Hot-rolled sheet/plate and strip
  • Hammer and drop forgings

BS EN 10084 applies to steels manufactured from the case hardening non alloyed or alloyed steels listed above, and supplied in one of the heat treatment conditions given for the different types of products covered, and in one of the surface conditions given.

European standards relating to steels complying with the requirements for the chemical composition outlined but that are supplied in other product forms or treatment conditions than given, or are intended for special applications, and European standards for similar steel grades are listed in the Bibliography.

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".

Special agreements shall be made when ordering non-deformed continuously cast semi-finished products.

In addition to the specifications of this European standard, the general technical delivery requirements of BS EN 10021 are applicable, unless otherwise specified.
