FERITSCOPE® FMP30 Measurement of the Ferrite Content in Austenitic and Duplex Steel Coating Thickness Material Analysis Microhardness Material Testing

2 FERITSCOPE® FMP30 Measurement of the Ferrite Content Chemical, energy and processing plants are often subject to heat, aggressive media and high pressure. These circumstances demand steel with high corrosion and acid resistance that are resilient even at high temperatures. If the ferrite content is too low, then the welded material is susceptible to hot-cracking, if the ferrite content is too high, the toughness, ductility as well as the corrosion resistance of the steel are reduced. For duplex steel, a ferrite deficit in the area of the weld seam results in stress corrosion cracking and...

3 Measurement influencing factors do not significantly affect the FERITSCOPE FMP30. Ferrite content measurements can be carried out regardless of the substrate material properties starting at a plating thickness of 3 mm. Corrective calibrations with customer-specific calibration standards or correction factors (included) can be used to take influences of the specimen shape (strong curvature), plating and substrate thicknesses into account. The calibration is always stored measurement-application specific in the respective application memory. Determination of the ferrite content in the weld...

6 FERITSCOPE® FMP30 Calibration and measurement method Magnetic induction method The FERITSCOPE FMP30 measures according to the magnetic induction method. A magnetic field generated by a coil begins to interact with the magnetic portions of the specimen. The changes in the magnetic field induce a voltage proportional to the ferrite content in a second coil. This voltage is then evaluated. All magnetic portions in the otherwise non-magnetic structure are measured, i. e., in addition to delta ferrite and other ferritic portions also strain-induced martensite, for example. A specific advantage...
