适用范围：1.1 This part of ISO 683 gives the technical delivery requirements for round and flat bars and wire rods manufactured from the alloyed steels listed in Table 2, intended for hot-formed and subsequently heat-treated springs or cold-formed and subsequently heat-treated springs. The products are supplied in one of the heat-treatment conditions given for the different types of products in Table 3, lines 2 to 6, and in one of the surface conditions given in Table 1.NOTE 1 Table 2 only considers steels which have gained certain international importance. This does not, however, mean that these are available in all industrial countries. In addition, a great number of other steels are specified in regional and national standards.NOTE 2 International Standards relating to steels complying with the chemical composition requirements in Table 2, but supplied in product forms or treatment conditions other than those given in 1.1 or intended for special applications, are given in the Bibliography.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.1.3 In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable.
