Abstract
The invention discloses nickel-molybdenum alloy steel which mainly comprises the following components in percent by weight: 8-30 percent of Ni, 10-30 percent of Mo, less than or equal to 0.5 percent of Si, less than or equal to 0.5 percent of C, less than or equal to 0.1 percent of Cu, less than or equal to 0.03 percent of P, less than or equal to 0.03 percent of S and the balance of iron. The low-price low-carbon steel serves as a raw material for producing the matrix material, the low-carbon steel has high ductility, and the residual sulfur S and phosphorus P in the raw materials are removed in the oxidization environment, so that stable chemical components of the matrix are guaranteed through a low-cost method, and high ductility is obtained.
Description
Technical field
The present invention relates to the anticorrosion Application Areas of steel alloy, the application of the nickel-molybdenum alloy steel of especially using about cable
.
Background technology
Cable is being brought into play more and more important effect in national economy, and has determined to a great extent use properties and the life-span of undersea cable for the alloy material of its manufacture.This traditional product is used for some time just to there will be pit in irregular shape. and there is the irised corrosion product of one deck on surface, and reason is remaining copper after the serious nickel removal of matrix; This corrosion condition is being subject to the increasing extensive concern of society.Therefore be directed to undersea cable and studied with the cupronickel wire rod, improve over-all properties and the processing characteristics of wire rod, to realizing industrialization, there is prior value.
Summary of the invention
In order to solve an above-mentioned difficult problem, the object of the present invention is to provide a kind of Ni-Mo alloy steel of high-temp and high-strength, suitably added the nickel that China has resources advantage in known formulations, improved technique simultaneously, reduce S(sulphur) P(phosphorus) content, reached the property indices of similar products at home and abroad fully.
The present invention is achieved by the following technical solutions: a kind of Ni-Mo alloy steel, and its major ingredient comprises following component (meaning with wt.%): Ni8-30, Mo10-30, Si≤0.5, C≤0.5, Cu≤0.1, P≤0.03, S≤0.03, surplus is iron.
The method of the clean nickel-molybdenum alloy of a kind of smelting high-purity comprises the following steps: first by scrap smelting to fusing point, then add successively copper, silicon, manganese, phosphorus, molybdenum, nickel starting material, or add again a kind of cobalt metal and get product.
The present invention, use the soft steel of low price as the raw material of producing above-mentioned substrate material, the ductility of soft steel is good, residual sulphur S, phosphorus P in raw material, the technique that employing is removed in well-oxygenated environment, thereby both guaranteed the chemical composition stability of matrix by method cheaply, obtained again higher elongation.
Embodiment
A kind of Ni-Mo alloy steel, its major ingredient comprises following component (meaning with wt.%): Ni8-30, Mo10-30, Si≤0.5, C≤0.5, Cu≤0.1, P≤0.03, S≤0.03, surplus is iron.
The method of the clean nickel-molybdenum alloy of above-mentioned smelting high-purity comprises the following steps: first by scrap smelting to fusing point, then add successively copper, silicon, manganese, phosphorus, molybdenum, nickel starting material, or add again a kind of cobalt metal and get product.
Claims (2)
