Abstract
Purpose. Corrosion rate of different smelting of the one grade of austenite Fe-Cr-Ni alloy from the specific magnetic susceptibility of austenite experimentally determine. Austenitic Fe-Cr-Ni alloy of ferrite did not contain. The magnetic state of austenite specific magnetic susceptibility is determined. Methodology. Scales with unipolar astatic magnetic system and the prism engagement to locate the specific magnetic susceptibility used. The corrosion rate was determined of the relative weight lossK=?m/(S??). Aggressive solution "aqua regia" to accelerate the chemical corrosion of samples used. Findings. Corrosion rate alloys 06HN28MDT (EI943) by the magnetic state of the austenite (specific magnetic susceptibility) is defined. The corrosion rate isreduced if a specific magnetic susceptibility of austenite decreases, and vice versa. Originality. Correlation dependence of the corrosion rate and the specific magnetic susceptibility (magnetic state) austenite of different smelting of the one grade alloy EI943 revealed.. Practical value. The results for identification of the corrosion rate in the austenitic Fe-Cr-Ni alloys can be used.
