Abstract

PURPOSE: To raise the sulfide resistance, setree and corrosion crack resistance, and hydrogen embrittlement resistance of steel by adding alloying elements, e.g., Mn, Cu, Ni, and Cr in a proper combination to a low-alloy steel to be used in apparatus for sour gas or sour oil.
CONSTITUTION: The low-alloy steel contains 0.03 to 0.18% C, 0.10 to 0.50% Si, 0.50 to 1.50% Mn, < 0.025% P, < 0.008% S, 0.20 to 1.00% Cu, 0.10 to 0.80% Ni, 0.20 to 1.00% Cr, and 0.01 to 0.10% sol. Al, and is used for the manufacture of apparatus for sour gas and sour oil. The inclusion of Mn, Cu, Ni, and Cr in the aforesaid amounts reduces the corrosion rate and hydrogen embrittlement of steel and also raises yield strength to 25 to 70 kg/mm2.
