ABSTRACT:
The present invention is directed to air-meltable, castable, workable alloys resistant to hot or cold chlorides and variety of chemical streams. The alloys consist essentially of, by weight, between about 20% and about 24% nickel, from about 22% to about 25% chromium, from about 5% to about 7% molybdenum, from about 0.7% to about 3.5% copper, up to about 0.08% carbon, up to about 0.35% nitrogen, up to about 0.8% columbian (niobium), up to about 1.5% manganese, up to about 1% silicon, and the balance essentially iron. Up to about 0.3% cobalt can also be present as an element naturally coexisting in certain ore deposits as a sister element to nickel and considered here to be part of the nickel content. The alloys of the present invention are of single phase austenitic matrices.
