SS400 in JIS G 3101 is supplied by many material manufactures, and the chemical properties other than those specified in JIS G 3101 may have different range in each material manufacturer. And so, the certified material testing reports (CMTRs) of SS400 procured in the past were reviewed, and the chemical properties and the tensile properties were organized. Based on the results, the applicability of SS400 to components of nuclear power generation facilities was evaluated.
