标准范围

本文件规定了用于冷镦或冷挤压并作为线材、线材或棒材交付的非合金钢和合金钢的要求。它还包含以下方面的具体要求:-非热处理用钢，直径为2 mm至100 mm（见附录A）；-直径为2mm至100mm的表面硬化钢（见附录B）；-淬火和回火用钢，包括直径为2mm至100mm的硼合金钢（见表C.3）（见附录C）；-奥氏体钢直径为0.8 mm至50 mm，铁素体钢直径为25 mm，马氏体钢直径为100 mm的不锈钢（见附录D）。本文件（附录A除外）适用于经过后续热处理的冷头或冷挤压零件的性能。由于零件的特性，在冷镦或冷镦时-挤压和随后未经热处理的条件在很大程度上取决于应用的冷镦或冷挤压条件，如有必要，这些条件取决于买方和零件制造商之间的协议。除本文件外，ISO 404的一般技术交付要求也适用。

This document specifies requirements for non-alloy and alloy steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It also contains specific requirements for:— steels not intended for heat treatment, with diameters from 2 mm to 100 mm (see Annex A);— case-hardening steels with diameters from 2 mm to 100 mm (see Annex B);— steels for quenching and tempering, including boron alloyed steels (see Table C.3), with diameters from 2 mm to 100 mm (see Annex C );— stainless steels with diameters of 0,8 mm up to 50 mm for austenitic steels, up to 25 mm for ferritic steels and up to 100 mm for martensitic steels (see Annex D).This document (except Annex A) is applicable to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. As the properties of the parts in the cold-headed or cold-extruded, and subsequently not-heat-treated condition, are largely dependent on the applied cold-heading or cold-extruding conditions, these are, if necessary, subject to agreement between the purchaser and the manufacturer of the parts.In addition to this document, the general technical delivery requirements of ISO 404 are applicable.
