DESCRIPTION

BS ISO 23825:2020

This standard BS ISO 23825:2020 Method for evaluating the nodularity of spheroidal carbides. Steels for cold heading and cold extruding is classified in these ICS categories:

77.140.10 Heat-treatable steels

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.
