Sometimes, knowing the exact ferrite content is essential. Especially wherever austenitic steels and duplex steels have to withstand heat, aggressive chemicals and/or high pressure.
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. But if you check the ferrite content with the FERITSCOPE® FMP30, you know for sure.
This handy instrument lets you measure the ferrite content anytime, anywhere – it’s fast, precise and non-destructive.
The advantages of the robust handheld device come to the fore when used in chemical plants, energy plants and process engineering plants.
The wide variety of Fischer probes makes it easy for you to measure the ferrite content, even if the spot is hard to reach. Just apply the probe; the FERITSCOPE® FMP30 does the rest.
The FERITSCOPE FMP30 measures the ferrite content in austenitic and duplex steel 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 magnetisable structure sections are measured i. e., in addition to deltaferrite also strain-induced martensite, for example, or other ferritic phases.
