表1 根据16原子团簇式设计的316不锈钢成分。合金编号中第一个字母表示类Ni元素的含量，第二个字母表示类Cr元素的含量，其中，B(bottom)表示下限，T(top)表示上限，M(medium)表示中值
Table 1 The designed compositions according to the 16-atom cluster formula of 316 stainless steel, with the alloy codes, cluster formulas, and compositions listed. The first letter of the alloy code indicates the content of Ni-like elements, and the second one indicates that of Cr-like elements, among which, B (bottom) means the lower limit, T (top) means the upper limit, and M (medium) means the medium values
