Abstract
PURPOSE: To enhance the hydrogen induced cracking resistance in wet environment contg. hydrogen sulfide by adding La to a steel contg. a prescribed amount of C, Si, Mn, S, Al, P and O in Fe in an amount satisfying a specified equation in accordance with the Si and P contents of the steel.
CONSTITUTION: The titled steel products consist of 0.02W0.2% C, 0.01W0.5% Si, 0.3W2% Mn, ≤0.01% S, 0.01W0.1% Al, <0.03% P, ≤40ppm O, La in an amount satisfying the equation and the balance Fe. The low alloy steel products are easily manufactured like general steel, have hydrogen induced cracking resistance, and are used mainly in environment contg. sulfide such as a crude oil transporting line, an oil well pipe or a crude oil tank.
