ISO 683-2-2012 pdf free download.Heat-treatable steels, alloy steels and free-cutting steels – Part 2: Alloy steels for quenching and tempering. 1.1 This part 01150 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, and — hammer or drop forgings (see Note 1) manufactured from the direct hardening alloy steels and the 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 8 and 9). The requirements for mechanical properties given in this part of ISO 683 are restricted to the sizes given in the relevant Table 8. NOTE 1 Hammer-forged semi-finished products (btooms, billets, slabs. etc.). seamless rolled rings and hammer-forged bars are in the following covered under semi-finished products or bars and not under the term ‘hammer and drop forgings”.

ISO 683-18-2014 pdf free.Heat-treatable steels, alloy steels and free-cutting steels – Part 18: Bright steel products. 1.1 This part of ISO 683 specifies the technical delivery requirements for bright steel bars in the drawn or peeled/turned condition and they are intended for mechanical purposes, for example for machine parts. The bright bars are subdivided into the following steel types: a) non-alloy general engineering steels; b) non-alloy free-cutting steels; c) non-alloy and alloy case-hardening steels; d) non-alloy and alloy steels for quenching and tempering; e) stainless steels. 1.2 In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
