Abstract
PURPOSE: To obtain an alloy for a high strength oil well pipe with superior stress corrosion cracking resistance by adding C, Si, Mn, P, S, sol. Al, N, Ni, etc. in a specified ratio.
CONSTITUTION: An alloy consisting of, by weight, 0.1W0.25% C, ≤1.0% Si, ≤2.0% Mn, ≤0.030% P, ≤0.005% S, ≤0.5% sol. Al, ≤0.30% N, 30W60% Ni, 15W35% Cr, ≤12% Mo and/or ≤24% W, and the balance Fe with inevitable impurities while satisfying Cr%+10Mo%+5W%≥110% and 7.5%≤Mo%+1/ 2W%≤12% is prepared. To said composition may be added ≤2% Cu and/or ≤2% Co, and/or 1 or ≥2 kinds of elements selected from ≤0.10% rare earth element, ≤0.20% Y, ≤0.10% Mg, ≤0.5% Ti and ≤0.10% Ca.
