Abstract
PURPOSE: To enhance the durability of the resulting titled alloy in the environment of an oil well by providing a specified composition consisting of C, Si, Mn, P, S, Al, Ni, Cr, Mo or W, and the balance Fe.
CONSTITUTION: This alloy for an oil well pipe with superior corrosion resistance, especially superior stress corrosion cracking resistance has a composition consisting of ≤0.1% C, ≤1.0% Si, ≤2.0% Mn, ≤0.030% P, ≤0.005% S, ≤0.5% Al, 35W60% Ni, 22.5W35% Cr, Mo and/or W in an amount satisfying equationsI, II, and the balance essentially Fe. To the composition may be added ≤1% Cu and/or one or more among ≤0.1% rare earth element, ≤0.20% Y, ≤0.10% Mg, ≤0.10% Ca and ≤0.5% Ti.
