Unformatted text preview: about .2 of the true strain at the onset of necking. For 1018 CD, the n value of about .04 is very close to the true strain value at the onset of necking of about .03. 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....
