Abstract
PURPOSE: To obtain a non-refined high tensile steel having strength and toughness almost equal to those of refined steel and improved weldability by reducing carbon equivalent of non-refined steel; off-setting a decrease in strength with the addition of B; and rolling the steel of a controlled compsn. at a temp. above Ar3 transformation point followed by proper slow cooling and air cooling.
