Conclusions
-
1.
Alloying of Kh25N16GVAR steel with molybdenum increases the strength and the corrosion resistance.
-
2.
Alloying of Kh25N16GVAR steel with tungsten decreases the resistance to prolonged exposure to high temperatures.
-
3.
The addition of 2.5% Mo and 4% W increases the solubility limit of these elements in Kh25N16GTAR steel, and this leads to the formation of intermetallic phases and to embrittlement of the steels heated to 700-1000°C.
