Austenitic Stainless Steel and Duplex stainless steels are the stainless steel with two-phase microstructure consisting of ferrite and austenite and the phase balance is known to determine the corrosion resistance of this material. If the ferrite content is too low, for example in the area of weld seams, this can lead to a loss in strength. On the other hand, too-high ferrite content reduces corrosion resistance, toughness and ductility.

KNDT ARABIA Co.Ltd have precise, handy and Non-destructive instruments available to measure the Ferrite content.
