Nowadays, a good corrosion resistance of lightweight steel is demanded for its application. However, due to the high contents Mn and C, which are always corrosion-susceptible elements in steels, conventional not desirable this mission. Although Cr widely believed be common alloying element improve most it considered ineligible using relatively content C. This because trade-off between mechanical properties by Cr. In recent years, rapid developments additive coating manufacturing have provided new possibilities both microstructural modulation steel. case, design certain chemical composition manufacturing, interesting clarify effects on To reveal it, present work, Fe–Mn–Al–Cr–Si–Mo–C alloyed with 4 wt%, 8 wt% 12 prepared. The resistances mechanisms Cr-alloyed steels 3.5 NaCl solution investigated electrochemical immersion tests. work may provide insights steel, especially directions manufacturing.
