Summary

  1. 1.

    Heating in a tunnel furnace (10 m long, pipes moving through at the rate of 0.4 m/min) at 1200–1230°C ensures the desired grain size (grades 3–7) in steam boiler pipes of Kh18N12T steel.

     
  2. 2.

    An increase in the heating rate during heat treatment decreases the difference in the grain sizes.

     
  3. 3.

    At lower heating temperatures the grains in steel containing titanium are smaller, while at higher temperatures they are larger, than in the steel without titanium.

     
  4. 4.

    At the same temperature the microstructure of Kh18N12T steel containing 0.44% Ti consists of larger grains than that of steel with 0.65% Ti.
