The 1045 HR value of n and true strain are about .22 and .12 respectively, differing only by about a tenth. And the 304 SS’ values for n and true strain at onset of necking are about .38 and 1.05, respectively. The 304 SS’ true strain at onset of necking is about 64% greater than its strain hardening exponent....
