FERITSCOPE® FMP30 Measurement of the Ferrite Content in Austenitic and Duplex Steel  Coating Thickness  Material Analysis

Measurement of the Ferrite Content Chemical, 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....

Simple and quick measurements It is easy to measure the ferrite content accurately when using the FERITSCOPE FMP30. Upon probe placement on the surface of the specimen, the reading is displayed automatically and stored in the instrument. The probe can also be placed onto hard to reach areas. For such applications, the instrument features an “external start” function to trigger the measurements with the push of a button. This is ideal for measurements in pipes, bore holes or grooves. Finding weld seams in polished surfaces is made easy through the “continuous display” instrument function. When...

Calibration and measurement method Calibration / Standards To obtain comparable measurement results, the instru‑ ments must be adjusted or calibrated using standards that can be traced to internationally recognised sec‑ ondary standards. For this purpose, the IIW (Inter national Institute of Welding, UK) developed sec‑ ondary standards that have been determined by the TWI (The Welding Institute, UK) according to the method described in DIN EN ISO 8249 and ANSI/AWS A4.2. Helmut Fischer offers certified calibration standard sets that are traceable to the TWI secondary standards for corrective and...
