标准摘要
[中文适用范围]: 本文件规定了一种基于比较图的显微照相方法,用于确定用于冷镦和冷挤压的非合金钢和低合金钢制成的盘条、线材或棒材退火后碳化物的球化程度。 碳含量范围高达 1.20 % C。 此外,附录 A 包括基于机器视觉的常规测量方法。 [外文原描述]: This document specifies a micrographic method based on comparison charts for determining the degree of spheroidisation of carbides after annealing of wire rod, wire or bars made of non-alloy and low alloy steels intended for cold heading and cold extrusion. The range of carbon content is up to 1,20 % C. In addition, Annex A includes a method based on machine vision for routine measurements.
