Description / Abstract:
This part of ISO 683 specifies the technical delivery
requirements for
-semi-finished products, hot formed, e.g. blooms, billets,
slabs (see Note 1),
-bars (see Note 1),
-wire rod,
-finished flat products,
-hammer or drop forgings (see Note 1)
manufactured from the case-hardening non-alloy or alloy steels
listed in Table 3 and supplied in one of the heattreatment
conditions given for the different types of products in Table 1 and
in one of the surface conditions given in Table 2.
The steels are, in general, intended for the manufacture of
case-hardened (see 3.1) machine parts.
NOTE 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
‘hammer and drop forgings'.
NOTE 2 For International Standards relating to steels complying
with the requirements for the chemical composition in Table 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 delivery
requirements or additions to them can form the subject of an
agreement at the time of enquiry and order (see annex A).
In addition to this part of ISO 683, the general technical
delivery requirements of ISO 404 are applicable.
