ABSTRACT:
Herein disclosed is an Ni-Cr-Fe alloy being substantially in the single phase of austenite and improved in resistance to stress corrosion cracking. The alloy contains, by weight; 0.03 to 0.12% of carbon; 0.2 to 4% of silicon; 0.1 to 3% of manganese; 12 to 45% of nickel; 15 to 35% of chromium; vanadium and/or aluminum, the total amount of vanadium and aluminum being in the range of 0.2 to 4.0%, titanium in an amount of at least 5 times the carbon content and up to 1% of the total composition, and/or niobium in an amount of at least 7 times the carbon content and up to 1% of the total composition, and/or zirconium in an amount of at least 7 times the carbon content and up to 1% of the total composition, and/or tungusten in an amount of at least 5 times the carbon content and up to 2% of the total composition, the total amount of titanium and/or niobium and/or zirconium and/or tungusten being in the range of 0.3 to 2%; if desired, copper and/ or molybdenum in a total amount of 0.3 to 4%; and the balance of iron. This alloy has outstanding utility as structural material of heat exchanger, such as U-shaped tube of the nuclear reactor.
