Ferrite Content Measurement
Ferrite Content Measurement

Measurement of the ferrite content: It is relevant to determine the ferrite content of austenitic and duplex steel and to determine the portion of deformation martensite in austenitic materials, according to DIN EN ISO 17655 and according to the Basler-Standard. 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.

Factors, which may influence the accuracy, must be taken into account individually by the user, such as the geometry of the sample, the thickness of claddings or the exterior form of the permeable structure.
