Conclusions

  1. 1.

    Alloying of type 60Kh18ANG16 chrome—manganese steel with molybdenum, niobium, tantalum and vanadium increases its intergranular corrosion resistance after provoking heating at 600–850°C since these elements tie up carbon in cooling of the steel from the molten condition into high-temperature, carbides and eliminate formation at the austenitic grain boundaries of type (Cr, Mn)23C6 chromium carbides causing intergranular corrosion.

     
  2. 2.

    Nitrides of the group IVA elements Zr and Ti (Hf) and also of Al, Ce, and B and carbides (carbonitrides) of the group VIA elements Cr and Mo and of the group VA elements Nb, Ta, and V have the greatest probability of formation in cooling of steel from the molten condition.
