Problems solved by technology

[0002] The existing corrosion-resistant alloy materials used on ships have been proved by many aspects such as use experiments to obtain satisfactory results in terms of mechanical properties, but they still have deficiencies: due to the high content of precious elements Ni, V, Mo, etc. need to be normalized or dispatched after rolling, which makes the production process complicated, high production cost, and poor welding performance

Abstract

An anticorrosion alloy material contains C (0.01-0.2%), Mn (0.3-1.6), Si (0.1-1.6), Al (0.01-0.08), P (0.01-0.06), Nb (0.01-0.09), Cu (0.01-0.5), Re (0.01-0.06), S (0.01-0.03) and Fe (rest), and is prepared from molten iron of blast furnace through pretreating, loading to another furnace, adding waste steel, fluorite and ore, deoxidizing for alloying, refining, conticasting, rolling and cooling. Its advantage are high anticorrosion performance and weldability and low cost.

Description

technical field [0001] The invention relates to the technical field of metallurgy, and relates to a corrosion-resistant alloy material. Background technique [0002] The existing corrosion-resistant alloy materials used on ships have been proved by many aspects such as use experiments to obtain satisfactory results in terms of mechanical properties, but they still have deficiencies: due to the high content of precious elements Ni, V, Mo, etc. need to be normalized or dispatched after rolling, which makes the production process complicated, high production cost, and poor welding performance. Contents of the invention [0003] The object of the present invention is to provide a corrosion-resistant alloy material, which has the advantages of good corrosion resistance, good welding performance and low production cost. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a corrosion-resistant alloy material...
