The Acid-resistivity of Fe-Cr-Mn Alloys. A series of corrosion tests of Fe-Cr-Mn alloys containing 6%, 14% 18.5% and 26% Cr with varying Mn content 1.82_??_12.45% and 0.03_??_0.25% of carbon, were carried out by the dip method. The corrosion was examined in 10% aqueous solutions of HNO3, HCl and H2SO4 at 25° and 40% aqueous solution of HNO3 at boiling temperature by measuring the loss in weight, and the extent of corrosion was expressed as mg/cm2, hour. The results were discussed by referring equilibrium diagram of the Fe-Cr-Mn system.
