High strength, austenitic, non-magnetic alloy

摘要

A cold-worked, high strength, non-magnetic, austenitic, ferrous alloy having high resistance to stress-corrosion cracking and hydrogen embrittlement. Composition of this alloy in weight percent is: }Manganese 17 to 23 }Chromium >6 to <10 }Carbon 0.35 to 0.8 }Silicon up to 1.5 }Nickel up to 2.75 }Molybdenum up to 3.5 }Vanadium up to 1.7 }Columbium up to 0.45 }Nitrogen up to 0.8 }Iron Balance } WITH CARBON PLUS NITROGEN 0.35 TO 0.8 AND THE MANGANESE PLUS CHROMIUM BETWEEN 24 AND 31.5. Also a large electrical generator with retaining and baffle rings of the alloy. Also a method of hardening this alloy by cold working and aging.
