Low-temperature steel yeeb nkab yog cov yeeb nkab steel siv los thauj cov pa roj los yog kua hauv qhov kub thiab txias. Nquag, nyob rau hauv ib puag ncig uas tsis tshua muaj kub, cov kav hlau zoo tib yam tuaj yeem ua nkig, ua rau tsis ua haujlwm. Cov kav dej kub tsis tshua muaj peev xwm tiv taus siab thiab hnyav nyob rau hauv ib puag ncig huab cua, thiab lawv cov khoom siv thiab siv muaj cov txheej txheem tshwj xeeb thiab cov qauv.
Cov khoom xaiv rau cov kav dej kub tsis tshua muaj steel feem ntau yog raws li nws lub zog zoo thiab toughness. Feem ntau hais lus, cov khoom siv ntawm cov kav dej kub tsis tshua muaj steel yuav tsum muaj qhov kub tsis tshua muaj zog, uas tuaj yeem ua kom ntseeg tau tias nws yuav tsis poob nws cov khoom siv hauv qhov kub thiab txias. Cov khoom siv feem ntau rau cov kav dej kub kub xws li A333 Gr.6 thiab A420 WPL6. Cov ntaub ntawv no tseem tuaj yeem tuav lub zog zoo thiab tawv ntawm qhov kub thiab txias thiab tau maj mam dhau los ua cov ntaub ntawv tseem ceeb rau cov kav dej kub qis.
Cov txheej txheem tsim khoom ntawm cov kav dej kub qis yog txawv ntawm cov kav hlau zoo tib yam. Thaum lub sij hawm tsim cov txheej txheem, manufacturers feem ntau yuav tsum tau them sai sai rau kev tswj ib tug tej yam raug kub thiab ultrasonic vuam tshuab los xyuas kom meej tias cov yeeb nkab steel muaj zoo toughness thiab lub zog nyob rau hauv qis kub ib puag ncig. Nyob rau tib lub sijhawm, nruj kev ntsuas tsis muaj kev puas tsuaj thiab kev ntsuas zoo yuav tsum tau ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov kav hlau steel nyob rau hauv qhov kub thiab txias.
Cov kav dej kub tsis tshua muaj steel yog siv rau hauv cov kav dej thiab cov cuab yeej siv rau cov kua dej uas tsis muaj qhov kub thiab txias xws li liquefied natural gas, liquefied petroleum gas, thiab low-temperature nitrogen. Hauv cov ntawv thov no, cov kav dej cryogenic tsis tuaj yeem tsuas yog tiv taus siab thiab hnyav, tab sis kuj xyuas kom meej tias qhov kub thiab txias ib puag ncig hauv cov kua dej tsis cuam tshuam rau cov khoom siv ntawm cov kav dej thiab cov khoom siv. Tsis tas li ntawd, cov kav dej kub kub kuj tseem siv dav hauv aerospace, marine engineering thiab lwm yam haujlwm.
Low-temperature steel yeeb nkab yog ib hom yeeb nkab steel tshwj xeeb uas siv los tiv thaiv kev kub ntxhov thiab hnyav nyob rau hauv qhov kub thiab txias. Nws yog tus cwj pwm los ntawm qhov zoo ntawm qhov kub thiab txias toughness thiab lub zog. Thaum tsim khoom thiab siv cov kav dej kub kub, cov qauv tsim nyog yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias lawv zoo thiab kev nyab xeeb. Cov kav dej kub tsis tshua muaj steel yog siv dav hauv cov roj liquefied thiab lwm qhov chaw.
