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.
Ferrite Content Measurement can be carried out in-house or on-site to meet your requirements.
