摘要
A Ni—Cr—Fe alloy with improved resistance to stress corrosion cracking in nuclear environments, the alloy comprising 23-28 wt % Cr, 25-35 wt % Ni, 0.03 wt % C, 0.70 wt % Si, 1.0 wt % Mn, 0.015 wt % S, 0.35 wt % Ti, 0.15-0.45 wt % Al, 0.75 wt % Cu, and balance Fe and incidental impurities. The alloy may be used in steam generator tubing of a nuclear reactor. A method of producing an article includes: providing the alloy as disclosed herein; forming the alloy into the article by cold working the alloy to 20%; and heat treating the article.
