Description

High-performance track vehicle austenitic stainless steel alloy and preparation method thereof
Technical field
The invention belongs to stainless steel alloy technical fields, and in particular to a kind of high-performance track vehicle austenitic stainless steel Alloy and preparation method thereof.
Background technology
In face of increasingly serious Environmental Protection Situation and to resource-effective rigors, the public friendship in city is greatly developed and perfected Entire body system has become many countries and regions in the world and copes with energy-saving one of the measure taken.Urban rail transit vehicles are made For the carrier of public transit systems, the lightweight of its own and long service life become the inexorable trend developed.
Currently, the Urban Rail Transit Development in China is quickly, has multiple cities and open or building city rail traffic, rail The demand of road traffic car surges.Stainless steel passenger car is high with bus body strength, corrosion resistance is good, maintenance cost is low, low energy consumption, ring The advantages that border pollution is small and handsome in appearance, meets the trend of rail vehicle lightweight and superior development, is urban rail car from now on The main direction of development.If using light-weight design again on the basis of stainless steel passenger car, car body gross mass is made further to drop It is low, about mitigate 40% or so than common steel vehicle weight, therefore lot of materials can be saved, conservation-minded society has emphatically to development The meaning wanted.
Invention content
It, can be with invention broadly provides a kind of high-performance track vehicle austenitic stainless steel alloy and preparation method thereof Meet high intensity, high-wearing feature and corrosion resistance requirement of the rail vehicle to material.Its technical solution is as follows:
A kind of high-performance track vehicle austenitic stainless steel alloy comprising following weight percent composition:C≤ 0.1%, P≤0.03%, S≤0.01%, Si 0.2-1.0%, Mn 3.0-6.0%, Cr 14-16%, Ni 4.5-5.5%, Cu 0.6-1.0%, N 0.3-0.4%, Nb≤0.1%, Ti≤0.1%, V≤0.1%, Ba≤0.01%, rare earth elements RE ≤ 0.1%, surplus Fe.
Preferably, the rare earth element is one or more of lanthanum, cerium, yttrium.
Preferably, the rare earth element is one or more of lanthanum, cerium, yttrium and one kind in praseodymium, neodymium, promethium, samarium Or it several is composed.
Preferably, the quality of any one or more element accounts for rare earth element total amount and is more than or equal in lanthanum, cerium and yttrium 99.5%.
A kind of preparation method of high-performance track vehicle austenitic stainless steel alloy, the technique include smelting, ingot casting Or ingot formation, hot rolling, cold rolling and roll after annealing acid pickling step.
Preferably, the smelting is specifically, using vaccum sensitive stove, electric furnace+AOD furnace, electric furnace+AOD furnace+external refining Any one of LF stoves technique smelts the other components in addition to rare earth element, and rare earth element, casting temperature are added before tapping casting Degree control is at 1500-1650 DEG C.
Preferably, the ingot casting or ingot formation use hammer cogging or continuous casting and rolling, heating temperature 1150-1250 DEG C, cogging initial forging temperature is 1100-1200 DEG C, and final forging temperature is 950-1050 DEG C.
Preferably, when carrying out hot rolling, blank heating temperature is 1150-1250 DEG C, and start rolling temperature is 1100-1200 DEG C, eventually It is 950-1050 DEG C to roll temperature.
Preferably, when carrying out cold rolling, cold roling reduction 47-82%.
Preferably, the annealing temperature for rolling after annealing pickling is 900-1050 DEG C.
Room-temperature yield strength of the conventional austenitic stainless steel under hot-roll annealing state is generally relatively low, and manufacturing enterprise is logical Normal way is that the martensitic structure of high intensity is obtained after being processed by aximal deformation value cold rolling, and the surrender of stainless steel is improved with this Intensity, but adjoint problem is that martensitic phase itself is hard and crisp, and stainless hardness of steel unavoidably brings extension while raising The reduction of rate and toughness.Therefore it is to avoid these problems, the reasonable distribution that the present invention passes through chromium, nitrogen and manganese element in steel, it is ensured that Nitrogen reaches solid solution strengthening effect to be dissolved state presence;Suitable rare earth, barium, niobium, vanadium and titanium elements are added simultaneously, are generated Refined crystalline strengthening and intercrystalline strengthening effect, these elements can reduce grain boundary defects, improve the binding force of crystal boundary, reduce the diffusion of crystal boundary Rate strengthens crystal boundary to slow down dislocation climb;Meanwhile rare earth element and barium can also be enriched in crystal boundary, and it is miscellaneous to reduce S, P etc. Prime element while improving grain boundary structure in the segregation of crystal boundary, improves grain-boundary strength, improves corrosion resistance.Therefore, the present invention is thin Crystalline substance ensure that steel has higher elongation percentage and toughness while reinforcing.
Using the above scheme, the present invention has the following advantages:
Alloy of the present invention considers the factors such as production cost and performance, have developed a kind of addition rare earth element, The alloying elements such as barium, titanium, vanadium and niobium are used based on the high-performance track vehicle of refined crystalline strengthening and micro alloying element complex intensifying Austenitic stainless steel alloy material.The austenitic stainless steel alloy of the present invention, can be used as trolley coach, railway freight-car and new energy The structure steels such as automobile.The room-temperature mechanical property of austenitic stainless steel alloy of the present invention is excellent, and tensile strength reaches as high as 1255MPa is far longer than SUS304 stainless steels, in addition, the present invention and gold also have preferable corrosion resistance.
