Abstract
A high strength low-alloy steel is subjected to a controlled rolling and accelerated cooling process to obtain minimum physical properties while achieving improved mill productivity. The alloy chemistry utilizes a low silicon, carbon, niobium, vanadium, titanium-containing steel composition which is hot worked and accelerated cooled under controlled conditions. The chemistry, controlled rolling and accelerated cooling allows for significant increase in the finishing rolling temperature thereby permitting high rolling output. The alloy chemistry includes a low-carbon grade which also has improved castability, formability and weldability.
