Abstract
PURPOSE: To enhance the COD value of the resulting titled steel by providing a specified composition contg. Si, Mn, Al, a very small amount of Nb, Ca or REM, a little C, a little P, a little S and a little O.
CONSTITUTION: This high tensile steel with a high COD value has a composition consisting of, by wt., ≤0.15% C, 0.05W0.60% Si, 0.5W2.0% Mn, ≤0.12% P, ≤0.003% S, ≤0.02% Nb, 0.01W0.10% T.Al, ≤0.003% O, one or more among ≤0.5% Cu, ≤1.0% Ni, ≤0.5% Cr, ≤0.5% Mo, ≤0.1% V, 0.0005W0.006% Ca and 0.001W0.03% REM, and the balance Fe with inevitable impurities. The degree of segregation (peak value / average value) of C in the thickness direction of the steel may be regulated to ≤1.5.
