Ferrite content is an important consideration in Stainless and Duplex Stainless Steels as it effects corrosion resistance and susceptibility to cracking. Industrial processing and chemical plants work at high temperatures and pressures, often with aggressive media, and stainless steel is often the material of choice for these applications. If the ferrite content of the steel is too low, then welding of stainless material may crack at elevated temperature or with high stress or vibration. Alternatively, if the ferrite content is too high, the weld may be weaker and corrode. NEXTAGEN ANALYTICS is a leading supplier of instruments for ferrite content measurement and can recommend the best instrument, probe and calibration standards for your applications.
