Abstract

A process for controlling austenite grain size in austenite processing through nano-scale precipitate engineering of TiN-NbC composites to produce thicker gage product of niobium microalloyed steel includes controlling the base chemical composition of a steel product to include 0.003-0.004 wt. percent nitrogen, 0.012-0.015 wt. percent titanium, 0.03-0.07 wt. percent carbon, and 0.07-0.15 wt. percent nobium; lowering the temperature of roughening to end the roughening operation in the temperature range of from about 980°C to 1030 °C; retaining greater than about 0.03 wt. percent niobium in solution in the matrix by rapid cooling of the product to enter the finish rolling operation below the temperature of no recrystallization, with an austenite grain size of about 30 microns; and applying reduced rolling reduction in the finish rolling operation.
