Description
Technical field
The present invention relates to a kind of high temperature resistant flue austenitic stainless steel.
Background technology
nullConsteel electric steelmaking process is a kind of new Electric Furnace Steelmaking carried out the nineties in 20th century，This electric furnace has continuous charging、Continuously pre-heating、Continuous melting、The feature of melting continuously，It is short that it has smelting cycle、Smelting energy consumption is low、Noise is little、The advantages such as cost of investment is low，It is a kind of electric furnace smelting advanced technology with stronger vitality and competitiveness in field of steel-making，But adopt Consteel electric furnace smelting high temperature resistant flue austenitic stainless steel this nickelic、High chromium and tungstenic mother liquor of stainless steel are but without precedent，The present invention can not only adopt the high temperature resistant flue austenitic stainless steel mother solution of Consteel electric furnace smelting by adjusting process parameter，And power consumption can be reduced、Shorten smelting cycle，P content can drop to less than 0.01% simultaneously，Greatly improve economic benefit.
Austenite series stainless steel is Fe～Cr～Ni series or Fe～Cr～Mn series.All there is stable excellent mechanical property from low temperature to high temperature.Carry out solutionizing heat treatment ametaboly point 920～1150 DEG C of temperature, rely on and be rapidly cool-off to become the nonmagnetic austenite structure with excellent decay resistance.Austenite series stainless steel is compared with martensite, ferrite series stainless steel, little etc. because being rich in extensibility and yield ratio (yield strength/tensile strength), so its processability is very superior.But its hardening property is big.Recently, utilize processing temperature dexterously, by the drop-down plutonic merit of situation in uniform temperature of the ultra-deep drawing that can not carry out in the past.
Austenite heat-resistance stainless steel is widely applied in boiler and flue, such as the steam boiler of thermal power generation, steamturbine industrial furnace and jet engine etc..They all at high temperature work, and bear various load, and they also contact with high-temperature steam, High Temperature Gas in addition, and surface is susceptible to high-temperature oxydation.310/310S is chromium nickle type austenitic stainless steel, owing to the addition of the chromium nickel than 304 higher amounts, and at high temperature can the generation of effective control oxide so that it is there is better high-temperature oxidation resistance and creep strength at higher temperature.The maximum operating temperature of 310S is up to 1200 DEG C, can at 1100 DEG C continuous firing, generally the hot environment below 1100 DEG C uses, but using the time short in hot environment, neoteric a kind of high temperature resistant flue austenitic stainless steel has higher high temperature endurance performance and pyro-oxidation resistance.
Hot properties: more than 500 DEG C, the intensity of other steel grades can sharply decline, and austenite series stainless steel still has higher intensity.Especially because it has good oxidative resistance, so being applicable to various worst hot cases.Because austenite series stainless steel is face-centered cubic lattice, significantly more superior than the ferrite series stainless steel of body-centered cubic lattic elevated temperature strength more than 600 DEG C.
Low-temperature characteristics: ordinary steel (ferritic steel) is a kind of high-strength material, but in low temperature, because its intensity and toughness all weaken, and be restricted on using.Martensite series, ferrite series and austenite series stainless steel, each superior characteristic is possessed respectively in room temperature and hot environment, but in low temperature environment, martensite series stainless steel and ferrite series stainless steel, the same with ordinary steel, cryogenic property is not good, and austenite series stainless steel, it is widely used because possessing excellent low-temperature characteristics.
300 series austenitic rustless steels (such as 304,316,317 etc.) are widely used in the fields such as oil, chemical industry, aerospace and the energy owing to all having good plasticity and toughness, cold and hot working performance and resistance to local corrosion performance under high temperature and extremely low temperature.Along with existingizationization development, many working condition requirements at high temperature have higher-strength and the special steel of good chemical, typical high temperature resistant stainless steel such as 06Cr25Ni20(310S) it is grow up by improving Cr, Ni content and improving stainless high temperature oxidation resistance simultaneously.
At present, stainless steel enterprises headed by Taiyuan Iron and Steel Co. and Baosteel production development all 310S heat-resistance stainless steel at home, to use in annealing furnace equipment, but 310S is primarily present and has the drawback that service life is short, for this situation, by the design of reasonable science and experimentation, the special austenitic stainless steel strand being used exclusively in high temperature flue can be outputed.The present invention by improving the content of chromium, nickel, reasonably add tungsten alloy metallic element, and strict control other alloying element contents, can make its material can life-time service in high temperature flue, save Master Cost for downstream client and increase economic efficiency.By novelty assessment report, paper and patent for the special austenitic stainless steel technical elements of high temperature resistant flue have not been reported, and processing technology and this patent require also there is basic difference.
