Abstract
The invention discloses an impact-resistant steel alloy material. The impact-resistant steel alloy material comprises the components by weight percentage: 1.7-3.2 percent of carbon, 70.4-81.9 percent of iron, 5.3-6.1 percent of zirconium, 5.6-6.2 percent of niobium, 6.1-6.3 percent of manganese, 6.7-7 percent of vanadium and 0.5-0.7 percent of other little impurities. With the structure, the prepared impact-resistant steel alloy material has the effects of stronger strength, stronger fatigue resistance and strong impact resistance.
Description
Technical field
The present invention relates to a kind of Steel Alloy, be specifically related to a kind of impact-resistant Steel Alloy material.
Background technology
Steel Alloy is a most widely used class non-ferrous metal structured material in the industry, in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry, widely apply, along with the develop rapidly of science and technology and industrial economy in recent years, demand to the Steel Alloy welding structural element is increasing, makes the Research on Weldability of Steel Alloy also thereupon deeply.The widespread use of Steel Alloy has promoted the Steel Alloy Development of Welding Technology, and Development of Welding Technology has been expanded the Application Areas of Steel Alloy again simultaneously, so the welding technique of Steel Alloy is just becoming one of focus of research.
The history in existing more than 100 year of steel alloy.The industrial alloy steel products that uses approximately is in latter half in 19th century morely.At that time because turnout and the usage quantity of steel constantly increased, and machinery manufacturing industry need solve the processing problem of cutting of steel, 1868 Britain forces uncommon special (R.F.Mushet) to have invented composition be the self-hardening steel of 2.5%Mn-7%W, cutting speed is brought up to 5 meters/minute.Along with development commercial and transportation, 1870 in the U.S. (1.5～2.0%Cr) to have built span at Mississippi be 158.5 meters bridge with chromium steel; Because difficulty takes place during tool member, after a while, some industrial countries use the bridge that nickel steel (3.5%Ni) is built large span instead.Meanwhile, some countries also are used for building warship with nickel steel.Along with the development of engineering, require to accelerate the velocity of rotation of machinery, high carbon chromium rolling bearing steel appearred in West Europe in 1901.Develop the rapid tool steel that the 18W-4Cr-1V type in 1910 again, further cutting speed is brought up to 30 meters/minute.As seen the appearance of steel alloy and development is the requirement that has adapted to the social productive forces development, and be particularly inseparable with the needs of machinofacture, communications and transportation and war industry.
Summary of the invention
The object of the present invention is to provide have that intensity is higher, fatigue resistance is strong and a kind of impact-resistant Steel Alloy material of the potent fruit of shock resistance.
Technical scheme of the present invention is: a kind of impact-resistant Steel Alloy material, described impact-resistant Steel Alloy material comprises elements such as carbon, iron, zirconium, niobium, manganese, vanadium and other small amount of impurities, each element wt proportioning is that carbon accounts for 1.7%-3.2%, iron accounts for 70.4%-81.9%, zirconium accounts for 5.3%-6.1%, and niobium accounts for 5.6%-6.2%, and manganese accounts for 6.1%-6.3%, vanadium accounts for 6.7%-7%, and other small amount of impurities account for 0.5%-0.7%.
In a preferred embodiment of the present invention, described small amount of impurities comprises copper and boron.
In a preferred embodiment of the present invention, described each composition weight proportion of impact-resistant Steel Alloy material is that carbon accounts for 2.3%, and iron accounts for 73.4%, and zirconium accounts for 5.4%, and niobium accounts for 5.7%, and manganese accounts for 6.1%, and vanadium accounts for 6.8%, and other small amount of impurities account for 0.6%.
A kind of impact-resistant Steel Alloy material of the present invention has that intensity is higher, fatigue resistance is strong and the strong effect of shock resistance.
Embodiment
Below in conjunction with preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
In one embodiment, a kind of impact-resistant Steel Alloy material, described impact-resistant Steel Alloy material comprises elements such as carbon, iron, zirconium, niobium, manganese, vanadium and other small amount of impurities, and each element wt proportioning is that carbon accounts for 1.7%-3.2%, and iron accounts for 70.4%-81.9%, zirconium accounts for 5.3%-6.1%, niobium accounts for 5.6%-6.2%, and manganese accounts for 6.1%-6.3%, and vanadium accounts for 6.7%-7%, other small amount of impurities account for 0.5%-0.7%, and described small amount of impurities comprises copper and boron.
Further specify, described each composition weight proportion of impact-resistant Steel Alloy material is that carbon accounts for 2.3%, and iron accounts for 73.4%, and zirconium accounts for 5.4%, and niobium accounts for 5.7%, and manganese accounts for 6.1%, and vanadium accounts for 6.8%, and other small amount of impurities account for 0.6%.
Can debug according to different ratios according to different demands, thereby reach different results of use.In steel except iron content, carbon and a small amount of inevitably silicon, manganese, phosphorus, element sulphur, also contain a certain amount of alloying element, alloying element in the steel has silicon, manganese, molybdenum, nickel, presses against, wherein one or more such as alum, titanium, niobium, boron, lead, rare earth, and this steel is steel alloy.The steel alloy system of various countries, different and different with separately resource situation, production and working conditions, once develop nickel abroad in the past, pressed against the steel system, China then finds the steel alloy system based on silicon, manganese, vanadium, titanium, niobium, boron, lead, rare earth.The iron-carbon that Steel Alloy constitutes at general carbon steel basis one or more an amount of alloying elements of interpolation.According to the difference of adding element, and take suitable complete processing, can obtain high strength, high tenacity, property such as wear-resisting, corrosion-resistant, low temperature resistant, high temperature resistant, nonmagnetic.Steel Alloy then enters in the sosoloid with atomic condition under hot conditions; Manganese, chromium, tungsten, molybdenum are carbide forming element, and wherein a part enters in the sosoloid with atomic condition, and another part forms the displaced type alloyed cementite; Aluminium, copper, nickel, cobalt, silicon etc. are not form the carbide element, generally are present in the sosoloid with atomic condition.The invention provides a kind of impact-resistant Steel Alloy material, have that intensity is higher, fatigue resistance is strong and the strong effect of shock resistance.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
