Txhawm rau txhim kho qee yam khoom ntawm cov hlau thiab yog li tau txais qee cov khoom tshwj xeeb hauv cov txheej txheem smelting txhob txwm ntxiv cov ntsiab lus hu ua alloying ntsiab.Cov ntsiab lus alloying feem ntau yog chromium, npib tsib xee, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, silicon, manganese, txhuas, tooj liab, boron, tsis tshua muaj ntiaj teb thiab lwm yam.Phosphorus, sulfur, nitrogen, kuj ua lub luag haujlwm hauv cov hlau nyob rau qee qhov xwm txheej.

Vanadium thiab carbon, ammonia, oxygen muaj kev sib raug zoo nrog kev tsim cov khoom tsim nyog ruaj khov.Vanadium nyob rau hauv steel feem ntau nyob rau hauv daim ntawv ntawm carbide tam sim no.Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho thiab ua kom zoo ntawm cov hlau, txo lub zog thiab toughness ntawm hlau.Thaum yaj nyob rau hauv cov khoom tov ntawm qhov kub thiab txias, nce hardenability;ntawm qhov tsis sib xws, raws li thaum carbides tsim, qis hardenability.Vanadium ua rau kom muaj kev ruaj ntseg ntawm hardened steel tempering thiab theem nrab hardening nyhuv.Cov ntsiab lus vanadium hauv cov hlau uas muaj, ntxiv rau cov cuab yeej siv siab ceev, feem ntau tsis ntau tshaj 0.5%.

Vanadium alloy steels nyob rau hauv dog dig low-carbon zog grain refinement los txhim kho lub zog thiab yield ratio tom qab normalizing thiab tsis kub yam ntxwv, txhim kho weldability.

Feem ntau, Vanadium alloy structural steels vim kev kho cua sov feem ntau yuav txo qhov hardenability, yog li cov qauv hlau feem ntau siv nrog manganese, chromium, molybdenum thiab tungsten, thiab lwm yam.Vanadium nyob rau hauv quenched thiab tempered steel yog tsuas yog los txhim kho lub zog ntawm cov hlau thiab cov yield ratio, grain refinement, thermal rhiab heev khaws.Carburizing steel vim tias nws tuaj yeem kho cov nplej, hlau tuaj yeem ncaj qha quenching tom qab carburizing, tsis muaj kev sib zog ntxiv.

Vanadium caij nplooj ntoos hlav steel thiab bearing steel tuaj yeem txhim kho lub zog thiab qhov sib piv, tshwj xeeb tshaj yog txhawm rau txhim kho qhov sib npaug thiab cov kev txwv elastic, kom txo tau qhov rhiab heev ntawm kev kho cua sov decarburization los txhim kho qhov zoo.Tsib chrome vanadium bearing steel, carbide, siab dispersion thiab kev ua tau zoo.

Vanadium cuab yeej steel lis refinement, txo tshav kub rhiab heev, nce tempering stability thiab hnav tsis kam, yog li ncua lub neej ntawm lub cuab tam.
