Ferrite Testing

Glacier has extensive experience in the use of equipment used to check ferrite content by measurement of magnetic permeability.

This technique is particularly useful in verifying material acceptability in castings, forgings, wrought products (pipes, fittings etc.) and weldments.

Ferrite testing is a fast, inexpensive, and accurate way to measure delta ferrite content in austenitic and duplex stainless steels. It is a technique used to measure the delta ferrite content in austenitic stainless steel and duplex stainless steel. The delta ferrite content is measured to better understand an austenitic or duplex stainless steel’s susceptibility to corrosion, susceptibility to solidification cracking and other types of material failure. Ferrite testing commonly employs magnetic induction as a means to measure the ferrite content of a material, although there are other methods that are used.
