%X For rapidly evaluating corrosion resistance to atmospheres containing SO\-2 as the main polluotands of low alloy steels, five selecded steels were tested by means of an immersion-wet-dry cycle test method,then the electrochemical conosron feature of the rusted steels after corrosion test was studied by XRD and SEM etc.The results showed that a decrement order of the corrosion resistance of the 5 steels is as follow: 06CuP,CortenA,09CuP,20Steel,A3.The corrosion rate of A3 steel was 2.49 times higher than 06CuP which was the most corrosion resistant among the 5 steels.The weigh loss of the 5 steels all followed exponential decay function: Y=Y 0+A e - t/B .The sequence of the factor - A/B of the 5 steels obtained by fitting calculation was insistent with that of corrosion resistance.
