FERITSCOPE® DMP30 Measurement of the Ferrite Content in Austenitic and Duplex SteelChemical, 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 reduction in strength.

Additional Information
The FERITSCOPE® DMP30 measures the ferrite content in austenitic and duplex steel according to the magnetic induction method. All magnetizable structure sections are measured i. e., in addition to delta ferrite also strain-induced martensite, for example, or other ferritic phases.It is suited for measurements according to the Basler- Standard and according to DIN EN ISO 17655. Areas of application are onsite measurements, e. g. of austenitic platings as well as weld seams in stainless steel pipes, containers, boilers or other products made of austenitic or duplex steel.Duplex steel is used increasingly in the chemical and petrochemical industries, e. g., for boilers and pipelines. A ferrite deficit in the weld seam area leads to strength reduction, an excess ferrite content to a reduction in toughness and ductility.In particular when welding duplex steel, the ferrite content in the welding area can easily assume unfavorable values either due to unsuitable welding filler materials or through poor heat input or heat removal. Only an onsite measurement can provide the assurance that the processing did not change the optimum ferrite content in an unfavorable manner at the expense of mechanical or corrosion-resistance properties.

Magnetic Induction Method
The FERITSCOPE® DMP30 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 of the magnetic induction method for measuring the ferrite content is that a sigma phase, i. e., a Fe-Cr precipitation, which has formed due to excess ferrite content and unfavorable cooling conditions, for example, is recognized correctly as a non-ferritic structural component. In comparison, erroneous interpretation of ferrite content is likely in a metallographic section where a sigma phase is not easily distinguished from a ferritic structure.
Simple And Quick Measurements
Even steel is not indomitable. Especially when austenitic or duplex steel is exposed to heat, pressure or aggressive environmental conditions. It is therefore important to always keep an eye on the ferrite content of welds – and the best way to do this is with a portable handheld gauge for material testing from Fischer. If the ferrite content is too low, strength losses will result. If the ferrite content is too high, this has a negative effect on corrosion resistance, among other things. How good it is to have access to a handheld gauge with which ferrite content measurements can be carried out quickly, easily and reliably on site. Measure the ferrite content with our handheld gauge FERITSCOPE® DMP30 and stay on the safe side!
