Abstract
The invention discloses a wear-resistant stainless steel wire. The wear-resistant stainless steel wire is at a diameter of 3.9-5.1mm and comprises the following components in a percent by mass: 0.01-0.03% of carbon, 13-17% of chromium, 7-8% of nickel, 0.1-0.12% of copper, 0.4-0.5% of phosphorus and the balance of iron. The steel wire provided by the invention is resistant to high temperatures, high in wear resistance and long in service life and radically solves the problems that the steel wire is easily worn and easily becomes rusty. The categories of alloy materials are increased, and the ratio of all material elements is regulated. As the nickel, the chromium, the copper, the phosphorous and the like are added into the materials for preparing the steel wire, a stainless steel finished product contains reasonable ratios of elements, including the nickel, the chromium, the copper and the phosphorous, the wear resistance and the corrosion resistance of the stainless steel material are greatly improved, and the service life is prolonged.
Description
Technical field
The invention belongs to metallurgical technology field, relate to a kind of abrasion-proof stainless steel silk.
Background technology
Existing rustless steel, has good corrosion resistance, all has application in various industries.Rustless steel has four kinds, and 1, ferritic stainless steel, its corrosion resistance, toughness and solderability improve with the increase of chrome content, and the stress corrosion performance of resistance to chloride is better than other kind rustless steels.2, austenitic stainless steel, is resistant to medium corrosion.3, martensitic stain less steel, intensity is high, but plasticity and solderability are poor.4, austenite-ferrite two phase stainless steel, the advantage having austenite and ferritic stainless steel concurrently, and there is superplasticity.
Rustless steel can be fabricated to stainless steel silk, is applied to the industries such as mining industry, oil, chemical industry, food, medicine, machine-building.Therefore the performance of stainless steel silk directly affects the performance of stainless (steel) wire.But the shortcomings such as the stainless steel silk on existing market also exists that intensity is low, wear no resistance, strong alkali-acid resistance difference, strongly limit its service life and range of application.
Such as publication number is the manufacture method that the Chinese patent of CN102828122A discloses a kind of stainless steel silk, comprises the following steps: 1) epithelium processes；2) dry；3) first time drawing and first time online bright annealing: the draft of first time drawing is 40～60%, and first time, online bright annealing temperature was 1000～1100 DEG C, and annealing speed is 3～9m/min；4) second time drawing and the online bright annealing of second time: the draft of second time drawing is 40～60%, and the online bright annealing temperature of second time is 1000～1100 DEG C, and annealing speed is 5～12m/min；5) third time drawing and the online bright annealing of third time: the draft of third time drawing is 45～75%, and the online bright annealing temperature of third time is 1000～1100 DEG C, and annealing speed is 5～12m/min.Although this steel wire tensile strength is good, extend, but not wear-resisting also not corrosion resistant.
Summary of the invention
Goal of the invention: for the shortcoming that the service life of stainless steel silk in prior art is shorter, the invention provides a kind of wear-resisting stainless steel silk.
Technical scheme: abrasion-proof stainless steel silk provided by the present invention, its diameter is 3.9～5.1mm, and its Ingredient percent is: containing carbon 0.01～0.03%, chromium 13～17%, nickel 7～8%, copper 0.1～0.12%, phosphorus 0.4～0.5%, all the other are ferrum.
We have discovered that in the steel that common ferrum-carbon is formed, add chromium and can be effectively improved hardenability and the tempering resistance of steel, improve the intensity of steel, and chromium can also reduce the activity of carbon, improve the leaching carbon of steel, and forming fine carbide, it is possible to decrease steel surface decarburization and graphitization in heating, rolling and heat treatment process are inclined to, and improve toughness and mar proof；But, during chromium too high levels, forming the carbide of chromium on the contrary in a large number, the bullet worsening steel subtracts performance and toughness.Therefore, in the present invention, controlling the content of chromium in stainless steel is 13～17% (percentage by weights), and optimum content is 16%
Meanwhile, adding a small amount of nickel, be resistant to various acid corrosion and stress corrosion, and property is tough and tensile, be magnetic and good plasticity, welding performance might as well；Higher intensity and antioxidation, resistance to combustion gas corrosion ability is had under 650～1000 DEG C of high temperature.In the present invention, controlling the content of nickel in steel is 7%～8%, and optimum content is 7.8%.
Furthermore it has been found that the addition copper of trace, phosphorus can improve the performance of steel atmospheric corrosion resistance.
One preferred version of the present invention is: described stainless steel Ingredient percent is: containing carbon 0.01～0.03%, chromium 16%, nickel 7.8%, copper 0.1%, phosphorus 0.4%, all the other are ferrum.
Further, we have found that if adding the niobium of trace in technique scheme, the corrosion resistance of steel can be strengthened, research finds, reason is in that the present invention is when carrying out heat treatment, presents the tissue of austenite+carbide, the existence of carbide, the corrosion resistance of steel is had a significant impact, and austenite heats at 450～850 DEG C, owing to crystal boundary precipitates out the carbide Cr of chromium23C6So that the chrome content near crystal boundary reduces, and causes intercrystalline corrosion.Therefore, we add the niobium of trace wherein, are combined formation NbC with carbon so as to preferential, and its stability is high so that chromium retains in the base, it is to avoid the lean chromium of crystal boundary, thus alleviating firm grain boundary corrosion tendency.Additionally, NbC precipitates out in Dispersed precipitate at intracrystalline, and not easily grow up under high temperature, it is possible to improve the elevated temperature strength of the present invention.For the present invention, when the content of niobium is 0.3～0.8%, the most properly, it is preferable that 0.37%.
A present invention preferred version containing chromium is: described stainless steel Ingredient percent is: containing carbon 0.01～0.03%, chromium 16%, nickel 4%, copper 0.1%, phosphorus 0.4%, niobium 0.37%, all the other are ferrum.
The invention also discloses the method that above-mentioned stainless steel silk obtains: first carry out pretreatment, then on rustless steel high-speed rod-rolling mill, stainless steel billet is rolled and makes the STAINLESS STEEL WIRE that diameter is 5.5～6.6mm while hot, STAINLESS STEEL WIRE is rolled into the coil of strip that internal diameter is 1000～1100mm by Laying head；Being put into by coil of strip and carry out heat treatment in heat-treatment furnace, with carrying out pickling after heat treatment, cold-drawn obtains abrasion-proof stainless steel silk.
Described pretreatment is proportioning raw materials, mixing, just refines, refine.By required composition, raw material being carried out proportioning herein, then mix, just refine, refine, described mixing, just refining, refine, for the conventional means of this area, without particular/special requirement.
Described heat treatment is temperature 1100 DEG C, is incubated 1.5 hours, water-cooled of coming out of the stove；
Described acid is a kind of mixed acid, and being specially mass concentration be 15% nitric acid is the acid that 5% Fluohydric acid. is made into mass concentration.
Described cold-drawn, experiences two processes, and the first process diameter reduces 1mm, and the second process diameter reduces 0.5mm.
Beneficial effect: steel wire provided by the present invention is high temperature resistant, anti-wear performance is high, long service life.Fundamentally solve the problem that steel wire is easy to wear, easily get rusty.Invention increases alloy material classification, have adjusted the proportional components of various material element, the material prepare steel wire increases nickel, chromium, copper, phosphorus etc., make in rustless steel finished product containing elements such as the nickel of rational proportion, chromium, copper, phosphorus, it is greatly increased the wear-resisting of stainless steel and corrosion resistance, extends its service life.
