The development process of special alloy steel series certified reference material (CRMs) was described. The reasonable smelting and forging technics were applied,the homogenity of the samples from deferent parts was studied, the certified values and expanded uncertainty of 15 elements were determined, linearity and consistency were tested. Also the CRMs were compared with other CRMs of the same kinds at home and abroad. The results showed that the homogeneity of developed certified reference materials was excellent with accurate certified values and good graded distribution.
