ABSTRACT OF THE DISCLOSURE An improved high-Ni, Fe-Ni alloy is disclosed comprising: Image with the balance comprising substantially Fe and additional inevitable impurities, provided that: (a) when Al is greater than 0.005 percent by weight, S is not greater than 0.005 percent by weight and Mn is 0.005 percent by weight or greater; and (b) when S is greater than 0.005 percent by weight, Al is not greater than 0.005 percent by weight and Mn is 0.005 percent by weight or greater. The improved alloy is non-sensitive to stress corrosion cracking and high temperature cracking, is structurally very stable and maintains low thermal expansion coefficient in the temperature range from room temperature to the temperature of liquefied natural gas.
