Conclusions
-
1.
The effectiveness of stabilizing annealing of austenitic chromium-nickel steel of the 18/8 type with titanium depends on the Ti/C ratio and the temperature of previous quenching.
-
2.
Stabilizing annealing has a negative influence at low Ti/C ratios. The higher the quenching temperature the higher the Ti/C ratio must be to prevent the negative influence of stabilizing annealing.
-
3.
At high provocation tempering temperatures the favorable influence of stabilizing annealing develops earlier, i.e., at lower Ti/C ratios.
-
4.
High resistance to intercrystalline corrosion of 18/8 steel with titanium as the result of stabilizing annealing is ensured if the Ti/C ratio is at least 6. For equipment operating in the dangerous range of temperatures where susceptibility to intercrystalline corrosion can develop we recommend 0Kh18N10T steel with Ti/C=6. At such temperatures the steel and welded joints must be subjected to stabilizing annealing to prevent intercrystalline corrosion.
