The laboratory and industrial tests of corrosion resistance of German ferritic alloys 13 CrMo 44 and 10 CrMo 910 are performed in the presence of chlorine-containing external deposits and the empirical kinetic equations are established. The X-ray structural analysis of oxide layers of these alloys and Russian pearlitic alloy 12Cr1MoV is executed. The comparative analysis of corrosion resistance of three alloys of superheaters of the PF oil shale boiler is presented.
