High-strength alloy for industrial vessels.

摘要

An austenitic nickel-iron-chromium alloy exhibiting high-strength, good corrosion resistance and having a low work hardening rate. The economic alloy is particularly useful for tubes and industrial vessels and, more particularly, heat exchangers and chemical and petrochemical equipment. The alloy includes e.g. 24 to 32% nickel, about 12 to 19% chromium, about 1 to 3.5% molybdenum, about 2 to 5.5% copper, up to about 2.5% titanium, up to about 1.5% manganese, up to about 0.1% cerium, and the balance mostly iron. Depending on the quantity of titanium, both age hardenable and non-age hardenable versions may be produced.
