Conclusions
-
1.
Steel 000Kh16N15M3 has a very low susceptibility to ICC only when the carbon concentration is below 0.02%. The depth of the attack is slight at tcr=650–700°C.
-
2.
Alloying with niobium eliminates susceptibility to ICC at carbon concentrations up to 0.03%.
-
3.
Up to 0.13% N has no effect on susceptibility to ICC in the steel with 0.003% C; at 0.03% C the susceptibility increases slightly.
-
4.
Alloying with silicon reduces the resistance to intercrystalline corrosion.
-
5.
Vacuum melts are somewhat more resistant to intercrystalline corrosion than open melts.
