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.
