工具钢

[中文适用范围]： 本文件规定了以下等级的锻造工具钢的要求： a) 非合金冷作工具钢； c) 合金热作工具钢； b) 合金冷作工具钢； d) 高速工具钢。 如果没有另外说明，本文件适用于按 6.2 和表 1 给出的表面和热处理条件之一供货的所有类型的热轧、锻造、冷拔或冷轧产品或粉末冶金生产的产品。 注：表 2、4、6 和 8 仅涵盖那些具有一定国际重要性的钢，但这并不意味着它们在所有工业国家都可用。 此外，地区、国家或公司标准还规定了许多其他工具钢。 当工具的耐热性特别重要时，例如用于热成型玻璃的工具，材料选择基于 ISO 4955。 [外文原描述]： This document specifies requirements for the following grades of wrought tool steels: a) non-alloy cold-work tool steels; b) alloy cold-work tool steels; c) alloy hot-work tool steels; d) high-speed tool steels. If not stated otherwise, this document applies to all types of hot-rolled, forged, cold-drawn or cold-rolled products or products produced by powder metallurgy, which are supplied in one of the surface and heat-treatment conditions given in 6.2 and Table 1. NOTE Tables 2, 4, 6 and 8 cover only those steels which have gained certain international importance, which does not mean, however, that they are available in all industrial countries. In addition, a number of other steels for tools are specified in regional, national or company standards. Where the heat resistance of the tools is of particular importance, as for example in the case of tools for hot forming glass, the material selection is based on ISO 4955.
