A process for producing a low pearlite steel containing small amounts of niobium and vanadium is described. Controlling rolling followed by a short annealing treatment results in grain refinement, precipitation strengthening, and matrix recovery, and produces plate with improved strength at increased toughness levels. The process, which has been successfully applied in practice, obviates the need for crystallisation control by continuous casting.
