Summary: | The invention discloses a high-strength and high-nitrogen iron-nickel-based corrosion-resistant alloy and a preparation method thereof, belongs to the technical field of corrosion-resistant alloys, and solves the problem that an iron-nickel-based corrosion-resistant alloy in the prior art is difficult to meet the requirements of high strength and high corrosion resistance of an oil well pipe material. The high-strength high-nitrogen iron-nickel-based corrosion-resistant alloy comprises the following components in percentage by mass: less than or equal to 0.015% of C, 25.0% < Cr < = 27.0%, 28.5% < Ni < = 29.5%, 0.20% < N < = 0.45%, less than or equal to 1.0% of Mn, 2.0% < Mo < = 3.0%, 0.6% < Cu < = 1.0%, less than or equal to 1.0% of Si, less than or equal to 0.03% of P, less than or equal to 0.01% of S and the balance of Fe. And the balance of Fe and inevitable trace impurities. The high-strength high-nitrogen iron-nickel-based corrosion-resistant alloy has good tensile strength, yield strength, hardness and |
