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毫米到100mm（见附录A）；—？表面硬化钢，直径为2毫米到100毫米（见附录B）；—？淬火和回火用钢，包括硼合金钢（见表C.3），直径为2毫米到100毫米（见附录C）；—？直径为0.8？的不锈钢mm到50对于奥氏体钢，mm，高达25对于铁素体钢，mm，高达100马氏体钢为mm（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。作为零件在低温下的性能-封头或冷挤压，以及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，这些条件须经买方和零件制造商之间的协议。

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.
