  • Fe-Mn vibration damping alloy steel having superior tensile strength and good corrosion resistance
    Patent number: 5891388
    Abstract: An Fe--Mn Vibration Damping alloy steel having a superior tensile strength is disclosed. The alloy steel consists of, by weight percent: 10 to 24% of Manganese(Mn); up to 0.2% of carbon(C); at least one element selected from the group consisting of 0.1 to 2.0% of Titanium(Ti), 0.1 to 2.0% of Molybdenium(Mo), 0.1 to 1.0% of Vanadium(V), and 0.1 to 0.7% of Tungsten(W), the element increasing a tensile strength of the vibration damping alloy steel; and remaining iron(Fe) and incidental impurities. Further, an Fe--Mn vibration damping alloy steel having a good corrosion resistance is disclosed. The alloy steel consists of, by weight percent: 10 to 24% of Manganese(Mn); up to 0.2% of carbon(C); at least one element selected from the group consisting of 0.1 to 4.5% of Chromium(Cr), 0.1 to 1.5% of Copper(Cu), and 0.1 to 1.1% of Niobium (Nb), the element increasing a corrosion resistance of the vibration damping alloy steel; and remaining iron (Fe) and incidental impurities.
