Over deze norm
ISO 683-1 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, and - hammer or drop forgings (see Note 1) manufactured from the direct hardening non-alloy steels and the non-alloy flame- and induction-hardening steels listed in Table 3 and supplied in one of the heat-treatment 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 quenched and tempered or austempered (see 3.2 and Note 2) and flame- or induction-hardened machine parts (see Tables 9 and 11), but can also be partly used in the normalized condition (see Table 10). The requirements for mechanical properties given in this part of ISO 683 are restricted to the sizes given in Tables 9 and 10. In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement between the manufacturer and purchaser at the time of enquiry and order (see 5.2 and Annex B). In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable.
