Chemical, utility and other processing plants areoften exposed to heat, aggressive media and highpressure. These circumstances require rust and acid resistant steel that can withstand mechanicalstress at high temperatures. If the ferrite content istoo low, the weld is susceptible to cracking under
heat, if the ferrite content is too high, the weld loosesits strength and corrosion resistance. For duplexsteel, a lack of ferrite in the area of the weld seam is an indicator of susceptibility to cracking undertension or vibration.
Measurement of the Ferrite Content in Austenitic and Duplex Steel
®
FERITSCOPE® MP30E
Features• Non-destructive measurement of the
ferrite content in a range of 0.1 to 110 FNor 0.1 to 80% Fe in austenitic and duplexsteel.
• Two instrument versions:FERITSCOPE® MP30E-S with bi-directio-nal serial interface,FERITSCOPE® MP30E-R with radio trans-mission (frequencies 868 MHz or 915 MHz).
• Simple measurement, even for complex specimen geometry.
• Battery or line operation (only MP30E-S).• Large LCD display for characteristic
measurement and statistical values as well as pictograms for status display and text lines for operator instructions.
• RS232 or radio transmission interface for data transfer to PC or printer (only with MP30E-S).
• Automatic measurement acceptance at probe contact or with external start.
• Acoustical signal at measurement acceptance.
• Statistical evaluation of test series and display of min., max. and mean value, number of measurements, standard deviation as well as date and time.
• Outlier control for automatic elimination of erroneous measurements
• Input of specification limits.• Free-running display with additional
presentation of the measurement as analog bar between selected specifica-tion limits.
• Memory capacity for max. 10,000 meas-urements in 1,000 blocks in up to 100 applications. Fixed or free block size selection.
• Measurement units selectable between WRC-FN and %Fe.
• 8 Display languages selectable.• No influence of the electr. conductivity
of the specimen.• Only one calibration required for the
entire practically relevant measurement range from 0.1 to about 90 FN. Measure-ment accuracy according to ANSI/AWS A4.2M/A4.2:1997 standard.
• Calibration with standards traceable to TWI secondary standards or with customer-specific standards.
Standard-Compliant MeasurementsThe FERITSCOPE® MP30E is suitable for measurements according to the Basler Standard or according to DIN 32514-1.
Application ExampleIncreasingly, the chemical and petrochemi-cal industries use duplex steel, e.g., for the reactor made of high corrosion resist-ant duplex stainless steel shown above. A ferrite deficiency in the weld beam may lead to cracks under the influence of ten-sion or vibration. However, when welding duplex steel, it is easy to bring the ferrite content in the welding area to unfavorable values, either because of unsuitable weld-ing additives or through wrong heat appli-cation or removal. Only a measurement onsite can ensure that the processing steps did not change the optimal ferrite content resulting in a decrease of the mechanical or corrosion resistant properties.
Measurement MethodThe FERITSCOPE® MP30E measures according to the magnetic induction method.A magnetic field generated by a coil enters into interaction with the magnetic compo-nents of the specimen. The changes in the magnetic field induce a voltage proportio-nal to the ferrite content in a second coil. This voltage is then evaluated. All magnetic components of the otherwise non-magne-tic structure are recognized, that is, in addition to delta ferrite and other ferritic components transformation martensite is also recognized.

Calibration/StandardsTo obtain comparable results, the instru-ments must be calibrated with standardsthat are traceable to internationallyaccepted secondary standards. For thisreason, the IIW (International Institute ofWelding, UK) developed secondarystandards that have been established by TWI (The Welding Institute, UK)according to methods described in DIN EN ISO 8249 and ANSI/AWS A4.2.
Helmut Fischer offers certified calibrationstandards for the corrective and mastercalibration that are traceable to the TWIsecondary standards. The standards in the Fischer calibration standards sets carry both the ferrite numbers FN and the %Fe values.
Influences of the component geometry(strong curvature, thickness of ferrite-con-taining coating, etc.) can be taken intoaccount through corrective calibrationswith customer-specific calibrationstandards or with correction factors(included with shipment). Normalizationand corrective calibration are storedapplication-specific in the respectiveapplication memory of the instrument.
