Abstract
The invention discloses stainless steel with super abrasion resistance. The stainless steel comprises a steel matrix and a tungsten carbide coating. The steel matrix comprises 10%-20% of chromium, 3%-5% of molybdenum, 1%-3% of tungsten, 1%-5% of manganese, 5%-10% of nickel and the balance iron and impurities. The surface of the steel matrix is covered with the tungsten carbide coating, and the thickness of the tungsten carbide coating ranges from 0.5 mm to 1 mm. Alloy elements are added, and the composition structure of the steel is optimized, so that the stainless steel has good abrasion resistance, oxidation resistance and the like.
Description
Technical field
The present invention relates to a kind of stainless material, be specifically related to the stainless steel that a kind of wear resisting property is good.
Background technology
Steel are nation-building and requisite valuable cargo of realizing the four modernizations, and it is widely used, various in style, have been deep into the every aspect in people's daily life.But a lot of steel used in daily life, when running into wet weather (the going back to Nan Tian of such as southern area), are easy to get rusty; In the industrial production, when steel parts exist each other contact and sliding friction time, wear phenomenon is obvious.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of and form structure by interpolation alloying element, optimization steel thus possess the stainless steel of good abrasion resistance.
To achieve these goals, present invention employs following technical scheme:
A kind of super abrasive stainless steel, comprises steel matrix and wolfram varbide coating; Chromium, the molybdenum of 3 ~ 5%, tungsten, the manganese of 1 ~ 5%, nickel, the surplus of 5 ~ 10% of 1 ~ 3% that described steel matrix contains 10 ~ 20% are iron and impurity; Described wolfram varbide coating covers the surface of steel matrix, and the thickness of wolfram varbide coating is 0.5 ~ 1mm.
Further preferably: chromium, the molybdenum of 4%, tungsten, the manganese of 3%, nickel, the surplus of 8% of 2% that described steel matrix contains 15% are iron and impurity.
Described impurity comprises carbon, phosphorus, the sulphur of trace.
Super abrasive stainless steel of the present invention, by adding the element such as chromium, molybdenum, tungsten, nickel, optimizes the alloy proportion of its steel matrix, improves that it is anti-oxidant, anticorrosive, wear resisting property; Be coated with the wolfram varbide coating of super abrasive at steel matrix surface, further increase its wearability.
Carry out some to the performance of some component elements that the present invention adopts below to introduce:
Chromium (Cr), chromium can improve hardenability and the tempering resistance of steel effectively, improve the intensity of steel, and chromium can also reduce the activity of carbon, improve the leaching carbon of steel, and form fine carbide, the steel surface decarburization in heating, rolling and heat treatment process and greying tendency can be reduced, improve toughness and wearability; But, during chromium too high levels, form the carbide of chromium on the contrary in a large number, worsen bullet subtractive energy and the toughness of steel.Therefore, in the present invention, the content controlling chromium in stainless steel is 10 ~ 20%(weight percent), optimum content is 15%.
Molybdenum (Mo), molybdenum is stainless steel non-corrosive, corrosion resistant key element; Therefore, molybdenum additives has very large impact to stainless performance, and a small amount of molybdenum is added among steel, and steel can be made to have very excellent performance, greatly can increase the wear resisting property of steel, increase the service life.Steel alloy can improve steel hardness, intensity and toughness containing molybdenum, and the good weldability of tool and corrosion resistance.After cast iron adds appropriate molybdenum, will greatly improve tension, bending resistance and fatigue resistance, also can improve the homogeneity of casting structure, this especially seems important to massive casting, these foundry goods are widely used in automobile making, pressure pipeline and mold etc., and in processing industry, molybdenum is used more extensive.Utilize thermal expansivity little, heat conduction be strong, molybdenum that high strength is good or molybdenum base alloy, die life significantly extends; Add the performance that alloying element just can improve them in Xiang Tie, steel and other metal, as hardenability, under intensity, erosion resistance and resistance to abrasive property.But during the too high levels of molybdenum, then worsen the plasticity of steel, toughness and processing characteristics.Therefore, in the present invention, the content that contriver controls molybdenum in stainless steel is 3 ~ 5%(weight percent), optimum optional 4%.
Tungsten (W), the physical features of tungsten is very strong, and in alloy, add a small amount of tungsten can greatly increase heavy alloyed intensity and wear resisting property.In the present invention, the content controlling tungsten in steel alloy is 1% ~ 3%, and optimum content is 2%.
Nickel (Ni), nickel has good over-all properties, can resistance to various acid corrosion and stress corrosion, and property is tough and tensile, is magnetic and good plasticity-, and welding property might as well; Under 650 ~ 1000 DEG C of high temperature, have higher intensity and anti-oxidant, resistance to combustion gas corrosion ability, be most widely used in superalloy, that hot strength the is the highest class alloy.In the present invention, the content controlling nickel in steel is 5% ~ 10%, and optimum content is 8%.
Super abrasive stainless steel of the present invention adopts conventional production process, is specially:
(1) raw material is carried out just refining; (2) refining; (3) cooling forming; (4) rolling; (5) quench; (6) tempering; (7) coating, namely obtains super abrasive stainless steel finished product.
Advantage of the present invention:
High temperature resistant, wear resisting property is high, long service life.First, the technical scheme that the present invention proposes fundamentally is solving the problem that steel are easy to wear, easily get rusty, molybdenum ore, nickel minerals, tungsten ore etc. are increased in the material preparing steel, make the element such as molybdenum, tungsten, chromium, nickel containing rational proportion in stainless steel finished product, greatly increase the wear resisting property of stainless steel, extend its work-ing life.Secondly, be coated with wolfram varbide coating on the surface of stainless steel, namely structurally improve further, again promote the wear resisting property of stainless steel, extend the work-ing life of stainless steel.
