Ferrite Measurement

Ferrite Measurement Chemical, power and process engineering plants are often exposed to heat, aggressive media and high pressure. This requires special corrosion- and acid-resistant steel that is mechanically resilient even at high temperatures. If the ferrite content in such steel is too low, the weldment is susceptible to hot-cracking, if the ferrite content is too high, the toughness and ductility as well as the corrosion resistance of the steel are reduced. In duplex steel, a lack of ferrite causes a reduction in stress corrosion cracking and strength in the weld area.
