The application belongs to the technical field of alloy forging preparation, and particularly relates to a 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings. The 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings improves the strength of the forging matrix, reduces the crack propagation ability of the material, improves the crack propagation work of the material, and improves the toughness of the forging matrix. The 05Cr17Ni4Cu4Nb forging preparation method for high-strength and high-toughness sealing rings has high operability, improves the high-strength and high-toughness of the 05Cr17Ni4Cu4Nb sealing ring forging after heat deformation, cooling and direct aging.

The application relates to the technical field of steel wires, and discloses a corrosion-resistant galvanized steel wire and a preparation method thereof. The corrosion-resistant galvanized steel wire is obtained by galvanizing a steel wire body through plating aid, and the steel wire body is composed of the following components in percentage by weight: C 0.15%-0.20%, Mn 0.28%-0.45%, Mo 0.15%-0.20%, Cu 0.12%-0.25%, W 0.05%-0.10%, Al 0.08%-0.12%, Ti 0.004%-0.016%, Sn 0.004%-0.015%, B 0.005%-0.01%, Y 0.005%-0.008%, S<=0.005%, P<=0.005%, and the balance is iron and inevitable impurities. Through the technical scheme, the problem that the tensile strength of the steel wire body in the galvanized steel wire needs to be improved in the related art is solved.
