Reducing the Variability of HSLA Sheet Steels (TRP 9807)
The sensitivity of the yield strength of a 70 ksi HSLA steel to changes in processing variables was investigated using a laboratory hot-rolling mill. Along with a detailed examination of the hot-rolled microstructures, auxiliary experiments were conducted to determine how the decomposition of the austenite phase and the occurrence of ultra-fine precipitate formation could account for the yield strength variability. A set of guidelines was recommended for the reduction of the yield strength variability.
