Abstract
The invention provides chromium-copper alloy steel. The alloy steel is characterized by comprising the following components in percentage by weight: 8 to 30 percent of Cr, 15 to 20 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 Fe. The anticorrosive material for cables, which has the advantages of low price, high accuracy and high yield, is high in hardness particularly at a high temperature, so that the abrasive resistance of the alloy steel in contact with welding wires and other surfaces can be greatly improved.
Description
Technical field
The present invention relates to the anticorrosion Application Areas of steel alloy, especially about composition material and manufacture method and the application of a kind of ODS copper-base alloys and chrome copper
.
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 chrome copper 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.
Technical scheme of the present invention is achieved in the following ways: a kind of chrome copper steel, and its major ingredient comprises following component (meaning with wt.%), it is characterized in that: Cr8-30, Mo15-20, Si≤0.5, C≤0.5, Cu≤0.1, P≤0.03, S≤0.03, surplus is iron.
The present invention includes following steps: first by scrap smelting to fusing point, add successively again copper, silicon, manganese, phosphorus, molybdenum, chromium starting material, perhaps add a kind of molybdenum again and get product, wherein composition material is comprised of the ODS copper-base alloys that is positioned at core and the chrome copper that is coated on described core periphery.
The volume percent of described ODS copper-base alloys is 10～70%, and the volume ratio of chrome copper is 30～90%.
The present invention, produce the impregnating material that the cable of low price, high precision, high yield is used, and particularly at high temperature, has very high hardness, greatly improved the wear resistance with contact surfaces such as welding wires.
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 chromium-copper gold 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 molybdenum and get product.
