1. Rationale
The first edition of this standard, published September 2012, contained errors in Table 1 and 7.3 which need to be corrected. In addition, this standard is for newer types of steel sheet that are used almost exclusively by the automotive industry, and which have been, and continue to be, developed by that industry in collaboration with the scientific community. Since publication, comments have been received from developers that the use of the name columbium for element 41 is archaic, and that ASTM, as they do, should use the modern and accepted name, which is niobium. As ASTM is endeavoring to have their steel standards used more widely by the automotive industry, this ballot proposes to change Cb to Nb in 6.1.2 and Table 2, so as to not be an irritant to this standard being seen as useful, relevant and up to date.
