冷镦和冷挤压用钢 交货技术条件 第1部分：非合金钢和合金钢

[中文适用范围]： 本文件规定了用于冷镦或冷挤压并以盘条、钢丝或棒材形式交付的非合金钢和合金钢的要求。它还列出了以下具体要求： — 不用于热处理的钢，直径为 2 毫米至 100 毫米（见附件 A）； — 直径为 2 毫米至 100 毫米的表面硬化钢（见附件 B）； — 直径为 2 毫米至 100 毫米的淬火和回火钢，包括硼合金钢（见附件 C）。 本文件（附件 A 除外）还适用于经过后续热处理的冷镦或冷挤压部件的性能。 注：用于冷镦和冷挤压的不锈钢由 ISO 4954-2 涵盖。 [外文原描述]： 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 lists the 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, with diameters from 2 mm to 100 mm (see Annex C). This document (except Annex A) also applies to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. NOTE Stainless steels for cold heading and cold extruding are covered by ISO 4954-2.
