Ferrite content measurements

1. Preface

In the chemical industry the stress-bearing members of containers,pipes,reactor vessels and other plant are usually made of austenitic steel or duplex steel or cladding of austenitic chromium-nickel steel．The residual ferrite content must be within a specific range compatible with the mechanical strength requirements or the item concerned．The HFE100 was developed to facilitateaccurate ferrite content measurements On welded seams and cladding items. It gives results that match for the standards of GB/T1954-2008,ISO 8249 and ANSI/AWS A4.2.
