Abstract
PURPOSE: To provide a highly tough and tensile steel useful for a line pipe or the like used in cold district by rolling the steel containing special amounts of C, Si, Mn, SolAl, Cr, Ni, Cu, Mn and W with higher than No.5 of γ grain size under predetermined conditions.
CONSTITUTION: After a steel containing 0.05W0.25% of C, less then 1.0% of Si, 0.5W2.0% of Mn, less than 0.080% of SolAl. 0.05W0.5% of one of Cr, Ni, Cu, Mo, W is treated with higher than No.5 of γ grain size, it is rolled at higher than 30% of pressure rate at Ar3W900°C., and rolled in transformation region during 5W50% transformation at the pressure rate of 10W60%. After the rolling process, it is air cooled or heat treated at less than Ar1 to thereby obtain a highly tough and tensile steel.
