These circumstances require rust and ders resistant steel that can withstand mechanical acid rost- und säurebeständige Stähle, die mechanisch bei high temperatures.

Measurement Method

The FERITSCOPE MP30 measures according to the magnetic induction method. A magnetic field generated by a coil enters into interaction with the magnetic components 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 components of the otherwise non-magnetic structure are recognized, that is, in addition to delta ferrite and other ferritic components transformation martensite is also recognized.

Application Example

Increasingly, the chemical and petrochemical industries use duplex steel, e.g., for the reactor made of high corrosion resistant duplex stainless steel shown above. A ferrite deficiency in the weld beam may lead to cracks under the influence of tension 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 welding additives or through wrong heat application or removal. 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.

Calibration/Standards

To obtain comparable results, the instruments must be calibrated with standards that are traceable to internationally accepted secondary standards. For this reason, the IIW (International Institute of Welding, UK) developed secondary standards 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 calibration standards for the corrective and master calibration that are traceable to the TWI secondary 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-containing coating, etc.) can be taken into account through corrective calibrations with customer-specific calibration standards or with correction factors (included with shipment). Normalization and corrective calibration are stored application-specific in the respective application memory of the instrument.
