  Type of diagram: TTS
  Chemical composition in weight %: No data.
  Note: Precipitation diagram. Time-temperature sensitization and intergranular corrosion.
  Time-temperature relationship for susceptibility to intergranular corrosion of 18%Cr-8%Ni
  austenitic stainless steel with various C contents as determined by the Strauss (boiling
  acidified copper sulphate) test. Below approximately 550^oC diffusion rates are too low for
  significant sensitization to accur in a short time, equally, above approximately 850^oC
  chromium carbide precipitation is not only slow but also diffusion rates are sufficiently
  high to replenish the Cr-deficient region. The removal of sensitization in this manner by
  prelonged holding at 900-950^oC is sometimes termed a 'stabilizing heat treatment'.
