| Abstract: | Conclusions To attain an effective increase of the strength properties of steels 40AF and 45AF, it is necessary to lay down rules for the content of vanadium within the limits 0.08–0.12%, of nitrogen 0.012–0.018%, of residual aluminum not more than 0.015%, normalizing and hardening temperature within the limits 940–960°C, tempering temperature 570–600°C.Foundry Institute (IPL), Academy of Sciences of the Ukrainian Production Association ZIL.
