ASTM A333 Qib 6 yog ib tus qauv kev qhia tshwj xeeb rau kev sib khi thiab welded carbon thiab alloy steel kav tsim feem ntau rau cov kev pabcuam kub tsawg. Cov qib kawm no yog cov khoom siv nyob hauv cov petrochemical, roj thiab roj av, thiab cov fais fab kev lag luam uas tuaj yeem poob rau ib puag ncig uas tuaj yeem poob rau qhov txias txias heev.
Qhov kev txhais cov yam ntxwv ntawm Astm A333 gr . 6 Yog nws qhov tshwj xeeb muaj kev cuam tshuam nyuaj ntawm sub- xoom} xoom. Cov kev siv tshuaj thiab kev tsim qauv yog tswj hwm nruj me ntsis kom ntseeg tau tias cov cuab yeej no. Tshwj xeeb, qib 6 kav yog yuav tsum tau mus rau Charpy V {}} IT}}}}}} 45℃f (-50 degree). Qhov no yuav tsum tau kuaj xyuas qhov kev lav tau hais tias cov khoom tuaj yeem nqus lub zog tseem ceeb thiab REIGN CARRACTEY, uas yog qhov kev siv tsis tseem ceeb hauv cov ntsuas dej tsawg.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm A333 gr. 6} yog ib qho chaw so almoy} Nickel yog qhov tseem ceeb tshaj plaws alloying uas ua rau muaj kev txhim kho qis qis - kub kev ntawm cov hlau. Cov tshuab ua haujlwm kuj tau hais tseg, kom muaj kev sib npaug ntawm lub zog (tensile thiab tawm lub zog) thiab ductility.
Cov kev siv rau Astm A333 Qib 6 Yeeb Nkab suav nrog:
* ** Tsawg {- Cov Khoom Siv Ntsuas Kub}
* ** Kev thauj cov roj cryogenic: ** Rau kev thauj cov roj av zoo li nitrogen, oxygen, thiab lwm yam roj uas tau khaws cia thiab ua haujlwm ntawm cryogenic kub.
* ** Cov nroj tsuag fais fab: ** Tshwj xeeb nyob rau hauv cov ntu ntawm cov nroj tsuag uas tej zaum yuav raug rau cov dej txias lossis ua kom dej txias.
* ** Offshore platforms: ** Qhov twg tuaj dej txias dej hiav txwv ib puag ncig yog qhov tseem ceeb npaum li cas.
Nws yog ib qho tseem ceeb kom nco ntsoov tias A333 qib 6 feem ntau piv rau ASTM A53 lossis A106 cov pa roj carbon steel; Txawm li cas los xij, nws txoj kev cuam tshuam zoo heev cov khoom tawv ntawm cov khoom siv kub tsawg kom pom tseeb nws thiab ua rau qhov kev xaiv qis qis {4} kev pabcuam kub. Muaj nyob rau hauv seamless thiab welded cov ntawv, nrog tom ntej kev kho cua sov ntawm welded kav dej kom ntseeg tau lub hauv paus weld ntais ntawv lub hauv paus khoom siv.
Hauv cov ntsiab lus, Astm A333 qib 6 yog tus hwm, ua tau zoo rau cov khoom siv qis thiab muaj kev nyab xeeb hauv kev xav tau cov khoom siv tsawg, ua rau nws muaj cov khoom siv kub tsis sib xws rau cov khoom siv niaj hnub no.
