Abstract

PURPOSE: To obtain steel products for a line pipe with high strength, high toughness and superior hydrogen sulfide cracking resistance by primarily rolling a slab having a specified relation among the contents of the principal components, followed by heat treatment and final rolling.
CONSTITUTION: A continuously cast slab or a bloomed slab consisting of ≤0.05% C, ≤0.50% Si, 1.0W2.0% Mn, 0.20W0.80% Cu, ≤1.0% Cr, ≤1.0% Ni, ≤0.05% Mo, a specified amount each of P, S, Al, N and Ca, 0.01W0.15% V, 0.0005W- 0.0050% B, one or more among a specified amount each of Nb, Ti and Zr, and the balance Fe and satisfying the relation of the equation is manufactured. The slab is primarily rolled at 1,100W1,350°C and 5W70% reduction ratio and held at the temp. for 1W100hr. After the heat treatment, final rolling to a prescribed plate thickness is carried out to obtain steel products maintaining strength, toughness and weldability necessary for a line pipe and having superior cracking resistance in wet H2S environment.
