Measurement of ferrite content with FERITSCOPE FMP30

FERITSCOPE measures the ferrite content in austenitic and duplex steels according to the magnetic induction method. The instrument recognizes all magnetic components, that is, in addition to delta ferrite, it also recognizes its transformed form of martensite. The instrument complies with the Basler standard and DIN32514-1 and is suitable for on-site testing. It can measure ferrite in austenitic coatings, stainless steel pipes, containers and boiler welds, and other products made from austenitic or duplex steels. content.

Basic principle of Ferite content measurement: magnetic induction method

FERITSCOPEFMP30 is measured according to the magnetic induction method. The magnetic field region generated by the coil interacts with the magnetic components within the workpiece, and the change in the magnetic field region produces an induced voltage in the second coil that is proportional to the ferrite content and then the voltage is evaluated. All magnetic components, that is to say, in addition to delta ferrite, including its transformed form martensite can be identified. The use of magnetic induction to measure ferrite content has a particular advantage. The sigma phase, Fe-Cr deposition, is formed by the fact that the ferrite content is too high and the cooling conditions are not correct, and is accurately identified as non-ferrite. On the other hand, in the metallographic section test, it is very difficult to distinguish the sigma phase from the ferrite structure, which will lead to a mis-evaluation of the ferrite content. FeriteScope FMP 30 uses magnetic induction method

Application examples for Ferite measuring

Duplex steels are increasingly used in the chemical and petrochemical industries. For example, the boiler vessels in Figures 1 and 2 are made of duplex stainless steel with high corrosion resistance. If the ferrite content at the weld is too low, it is easily broken when subjected to tension or vibration. However, when welding duplex steels, the ferrite content at the weld is very likely to exceed the standard due to improper soldering additives or heat treatment. Only on-site testing ensures that the process does not change the ferrite content and prevents mechanical or corrosion resistance.

FeritScope FMP30 Calibration / standard film

In order to obtain comparable results, the instrument must be calibrated with a secondary standard that can be traced back to the international standard. To this end, IIW (British International Welding Association) has developed a secondary standard sheet manufactured by the British Welding Society in accordance with the DIN EN ISO 8249 standard and the ANSI/AWS A 4.2 standard. HelmutFischer provides certified calibration standards for customer calibration of the instruments, which can be traced back to the TWI secondary standard. Two units are indicated on the standard sheet: ferrite number FN and percentage content %Fe. The effect of the workpiece geometry (curvature, thickness, etc.) on the measurement can be reduced by setting a correction factor prior to shipment or by customizing a standard sheet calibration instrument. Different calibration information is stored in different applications.
