Abstract
An austenitic, age-hardenable nickel-iron-chromium alloy exhibiting high-strength, good corrosion and polythionic acid resistance and having a low work hardening rate. The economic alloy is useful for industrial vessels such as heat exchangers, chemical and petrochemical equipment and, more particularly, tubes. The alloy includes about 25-29.5% nickel, about 14.5-17.5% chromium, about 2-3.5% molybdenum, about 2-5.5% copper, about 1-5% titanium plus aluminum, up to about 1.5% manganese, up to about 0.1% cerium, and the balance mostly iron.
