    The goal of this paper is to study the effect of high temperatures action on the specific magnetization value of 12X18H9 and 12X18H9T steels. Steels in form of plates 10 x 5 mm with thickness of 5, 6, 8 and 10 mm widely used in nuclear engineering were selected as samples for research. Experimental techniques, such as elemental analysis, diffraction backscattered electrons, X-ray analysis, measurement of specific magnetization in the 80 - 1100 K temperature range in a magnetic field with the induction of 0.86 T, the study of specific magnetization in a magnetic field with B = 14 T at a temperature of 300 K and the magnetization measurement with magnetodynamic type converter were applied. The X-ray diffraction studies have shown that the main components of stainless steels 12X18H9 and 12X18H9T are FeNi and NiCrFe phase. It was found that the main phase is ferromagnetic FeNi. The presence of FeNi phase was confirmed by diffraction backscattered electrons method (EBSD). The correlation of the specific magnetization value with the content of FeNi phase amount was determined. It was revealed that the magnetization in saturation of the test steels is practically absent in magnetic fields with induction up to 14 T. It was shown that the magnetic properties of the studied samples are due to both particles with ferromagnetic properties and paramagnetic clusters with superparamagnetic state characteristics. The comparison of the results of the specific magnetization measurement of 12X18H9T and 12X18H9 steel with a magnetodynamic converter data at room temperature shows that this method has a high sensitivity (0.016% in volume) and may be used for the quantitative determination of the ferromagnetic component.
