Austenitic, Duplex, Super-duplex stainless steels require adequate proportion of ferrite in the product to obtain acceptable corrosion resistance and strength and especially resistance to Stress Corrosion Cracking (SCC).

In order to guarantee the acceptable ferrite content in the final product, ferrite measurements are performed on the actual product using Fisher Feritscope MP30.

Ferrite measurement using Fisher Feritscope is a non-destructive test method which assures the quality of the product without the need of expensive laboratory based destructive test methods.
