Abstract
PURPOSE: To obtain highly tough non-heat treated H-shaped steel having excellent impact characteristics in the direction of thickness at its flange portion by controlling the composition of steel, heating temperature, and the temperature of flange portion after completion of hot rolling.
CONSTITUTION: The steel, containing less than 0.08% C, less than 0.60% Si, less than 2.0% Mn, 0.01 to 0.08% Al, less than 0.008% S, more than 10 ppm Ca, and Fe, is heated to 1000 to 1200°C and then rolled, where the final pass temperature of H-shaped steel's flange portion at the rough universal mill is regulated to 780 to 900°C. Then, it is formed into H-shaped steel by the usual finishing universal mill to obtain steel product. The H-shaped steel, featuring excellent anti-impact characteristics in the direction of thickness at the flange portion, is effectively applicable to the fields of large-size steel structures of earthquake resistance, etc.
