The chemical composition certified materials of 35CrNi3Mo were prepared with the same smelt technology of ultra high strength steel. Techniques of preparing certified materials,homogeneity test and stability test were analyzed. The results showed that the homogeneity and stability of the chemical composition certified materials were fine. A cooperative certification was conducted by eight labs. The uncertainty of determination results was evaluated. The relative expanded uncertainty of each component was less than 13%.
