Abstract
The resistance to general corrosion and stress corrosion cracking of manganese-nickel alloys are improved through the incorporation of special amounts of chromium and iron.
Claims8
A substantially non age-hardenable manganese-nickel alloy composition characterized by both good hot and cold workability and in having been satisfactorily hot worked or cold worked or both and being further characterized by improved resistance to both general corrosion and stress-corrosion cracking, the alloy consisting of about 8 to 14% nickel, about 8 to 15% chromium, about 35 to 55% iron and the balance essentially manganese, the manganese constituting at least about 24% of the alloy.
A substantially non age-hardenable manganese-nickel alloy composition characterized by both good hot and cold workability and in having been satisfactorily hot worked or cold worked or both and being further characterized by improved resistance to both general corrosion and stress-corrosion cracking and consisting of 5 to 12% nickel, 5 to 15% chromium, from 30 to 60% iron, and the balance essentially manganese, the manganese being from 18 to 55%.
A substantially non age-hardenable manganese-nickel alloy composition characterized in having been satisfactorily hot worked or cold worked or both and being further characterized by improved resistance to both general corrosion and stress-corrosion cracking, the alloy consisting essentially of from 5 to 15% nickel, 5 to 12% chromium, 30 to 60% iron, up to 2.5% copper, up to 2% lead, up to 1% silicon, up to 0.25% carbon and the balance essentially manganese, the manganese being from 18 to 55%.
