Abstrakt: 1.The effectiveness of the annealing medium depends on the original composition of the metal in terms of impurities and nonmetallic inclusions.2.The highest magnetic properties of alloys 50NP and 79NM (OI heats) were obtained by vacuum annealing at 10-3–10-4 mm Hg or annealing in hydrogen with a dew point no higher than -50°.3.To obtain the highest possible magnetic properties of the EBR heats requires vacuum annealing at a pressure<10-4–10-5 mm Hg or in hydrogen with a dew point no higher than -65°.
