FERITSCOPE® MP30E® Measurement of the Ferrite Content in Austenitic and Duplex Steel Chemical, utility and other processing plants are often exposed to heat, aggressive media and high pressure. These circumstances require rust and acid resistant steel that can withstand mechanical stress at high temperatures. If the ferrite content is too low, the weld is susceptible to cracking under heat, if the ferrite content is too high, the weld looses its strength and corrosion resistance. For duplex steel, a lack of ferrite in the area of the weld seam is an indicator of susceptibility to cracking under tension or vibration. NDT SUPPLY.COM, INC.

Application Example Features • Non-destructive measurement of the ferrite content in a range of 0.1 to 110 FN or 0.g. • Measurement units selectable between WRC-FN and %Fe. The changes in the magnetic field induce a voltage proportional to the ferrite content in a second coil. when welding duplex steel. Measurement Method. FERITSCOPE® MP30E-R with radio transmission (frequencies 868 MHz or 915 MHz). • Simple measurement. All magnetic components of the otherwise non-magnetic structure are recognized. the line adapter and the charger fit in the practical carrying case. Fixed or free block size selection. in addition to delta ferrite and other ferritic components transformation martensite is also recognized. the chemical and petrochemical industries use duplex steel. either because of unsuitable welding additives or through wrong heat application or removal. using the example of an austenitic plating..1 to about 90 FN. max. 1: Ferritic portion of structure 2: Steel substrate material 1 2 Basic operation of the magnetic induction measurement method.

Measurement Method The FERITSCOPE® MP30E measures according to the magnetic induction method. Only a measurement on site can ensure that the processing steps did not change the optimal ferrite content resulting in a decrease of the mechanical or corrosion resistant properties. standard deviation as well as date and time. • Statistical evaluation of test series and display of min.

However. • Outlier control for automatic elimination of erroneous measurements • Input of specification limits. • Only one calibration required for the entire practically relevant measurement range from 0.000 blocks in up to 100 applications.
