Abstract The corrosion rates of 17 steels were gray clustering analyzed.The kinds of steel were as objective,test station as cl ustering index,high,middle and low as clustering gray number，the critical value of white function confirmed by the mean and standard deviation of the rates of all steels at same test station.Normalized clustering coefficients were obtained .The weathering performances of low alloys were judged with normalized clusterin g coefficient.The effects of chemical composition on the weathering performance were analyzed.It was proved that this method can be used in discovery of the sim ilar experimental data.

Key words: gray clustering atmospheric corrosion steel data analy sis chemical composition
