Method for evaluating the nodularity of spheroidal carbides — Steels for cold heading and cold extruding ISO 23825:2020

General information

60.60 Standard published   Dec 23, 2020

ISO

ISO/TC 17/SC 4 Heat treatable and alloy steels

International Standard

77.140.10   Heat-treatable steels

Scope

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.
