As raw material for metal-melt treatment, the steel containing 20.3% Cr; 11.2% Mn; 7.1% Ni; 1.46% Mo; 0.33% Si; and 0.05% C was used. As-cast samples of nitrated chromium (ФХH10 and ФХH20 grades) were used as alloying additives. The compositions of grades are 85.7% Cr; 8.0% N, and 73.9% Cr; 16.1% N, respectively. Experiments were carried out in high-temperature laboratory unit at 1500<span class="s1">∘</span>C. It was found that the degree of nitrogen transfer into steel reaches up to 84% at the application of as-cast specimen of nitrated chromium containing 8% of nitrogen and 1 min exposure time after addition to ferroalloy. Further high-temperature soaking of nitrated steel causes a dropdown of nitrogen concentration due to thermal dissociation of existed nitrogen-containing compounds in the melt and exhalation in gas phase. This prevents nitrogen transfer into the steel. It was demonstrated a possibility in principle of obtaining of chrome-manganese steel containing about 0.4–0.6% of nitrogen at melt alloying by nitrated chromium in air atmosphere at exposure time up to 15 min.</p> <p class="p1"><span class="s2">Keywords: </span>metallurgy, nitrogen, chromium, steel, digestion degree, physicochemical characteristics</p&gt;}, number={1}, journal={KnE Materials Science}, author={Andreevich Smirnov, L and Vadimovich Zayakin, O and Ivanovich Zhuchkov, V and Sergeevich Oryshchenko, A and Yurievich Kalinin, G}, year={2019}, month={Mar.}, pages={246–253} }
