TEXT: Tho investigated steel was produced in an acidically
lined induction furnace and had the following composit 'ion:
0-31~~ C, 1.100% Cr, 1.14% mn, 1.12% Si, 1.40% Ni, o.o26% P,
o.o24% s. The thermomechanical treatment was carried out Drior
to the ordinary quenching and tempering. The blanks were heated
to 1050-1100*C, forged and then the influence was investigated of
the degree of doformation, the temperature of terminating the
forging, the cooling and the annealing condi'tions. After forging,
all the blanks were subjected to the same annealing conditions
and then specimons were produced which were quenched from 9000C
and tempered at 5000C. A aharp drop in the impact strunfth.was
observed for tho range of tempering temperatures 425-625 C-

TRANSLATION: The addition of up to 0.3$ niirogen noticeably increases heat
resistance. Increasing the nitrogen content in alloys is desirably, but limited
due to thelcamplication of sample smelting technology& The addition of boron
up to its solubility limit gives even better results. The addition of boron with
the separation of the excess phases decreases heat resistance. The addition
