1Ā Ā Ā Scope This document specifies the technical delivery requirements for
ā semi-finished products, hot formed, e.g. blooms, billets, slabs (see NOTEĀ 1),
ā bars (see NOTEĀ 1),
ā wire rod,
ā finished flat products, and
ā hammer or drop forgings (see NOTEĀ 1)
manufactured from the case-hardening non-alloy or alloy steels listed in TableĀ 3 and supplied in one of the heat-treatment conditions given for the different types of products in TableĀ 1 and in one of the surface conditions given in TableĀ 2. The steels are, in general, intended for the manufacture of case-hardened machine parts.
NOTEĀ 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are covered under semi-finished products or bars and not under the term āhammer and drop forgingsā.
NOTEĀ 2 For International Standards relating to steels complying with the requirements for the chemical composition in TableĀ 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.
In special cases, variations in these technical del...
