Popis:	1. Raising the molybdenum content from 0.9 to 3.7% in austenitic steel with 19% Cr, 10% Mn, 7% Ni, and 0.30% N raises the ultimate strength to 93 kg/mm2 and the yield strength to 58 kg/mm2. 2. In the steel not containing molybdenum, tempering at 800°C leads to the formation of M2N and M23C6; the addition of molybdenum in amounts over 2.1% leads to preferential formation of σ phase during tempering. 3. Raising the carbon content from 0.01 to 0.11% lessens the tendency to form σ phase in austenitic steel with 2.5% Mo and leads to formation of M23C6 carbide.
